Fresh lemon, herbs, and a light dressing brighten everything up so it never tastes heavy. The ingredients are flexible, affordable, and easy to find, and the bowl packs well for work or school.

Ingredients

• 2 cans tuna in water or olive oil, drained (about 10–12 oz total)
• 1 large ripe avocado, diced
• 2 cups cooked grain base: quinoa, brown rice, farro, or cauliflower rice
• 1 cup cherry tomatoes, halved
• 1 small cucumber, diced
• 1/4 small red onion, thinly sliced
• 1/4 cup chopped fresh herbs: parsley, cilantro, or dill
• 1/4 cup crumbled feta or shredded Parmesan (optional)
• 1 cup leafy greens: baby spinach, arugula, or mixed greens
• 1/4 cup toasted nuts or seeds: pumpkin seeds, sliced almonds, or sunflower seeds
• 1 lemon (zest and juice)
• 2–3 tbsp extra-virgin olive oil
• 1 tsp Dijon mustard
• 1 small garlic clove, grated or minced
• 1/2 tsp honey or maple syrup (optional, to balance acidity)
• Salt and black pepper, to taste
• Red pepper flakes, to taste (optional)

Step-by-Step Instructions

1. Cook your base: Prepare quinoa, rice, or your preferred grain according to package directions. Let it cool slightly.

   For a low-carb option, use cauliflower rice—lightly sauté with a pinch of salt for 3–4 minutes.

2. Make the dressing: In a small bowl, whisk lemon juice and zest, olive oil, Dijon, garlic, honey (if using), salt, and pepper. Taste and adjust acidity and salt.
3. Prep the veggies: Halve tomatoes, dice cucumber, thinly slice red onion, and chop herbs. Pat veggies dry with a paper towel so the bowl doesn’t get watery.
4. Flake the tuna: Drain the tuna well.

   In a mixing bowl, gently flake with a fork. Season with a pinch of salt, pepper, and a spoonful of dressing to moisten.

5. Assemble the bowls: Divide greens and grains between two to three bowls. Add tuna, tomatoes, cucumber, red onion, and avocado on top.
6. Add crunch and cheese: Sprinkle nuts or seeds and feta (if using).

   The mix of textures makes every bite interesting.

7. Dress and finish: Drizzle the remaining dressing over each bowl. Top with fresh herbs and a pinch of red pepper flakes if you like heat.
8. Serve: Enjoy right away, or chill for 15 minutes to let flavors meld. If packing for lunch, add avocado and dressing just before eating.

Keeping It Fresh

Avocado browns quickly, so add it right before serving.

If you need to prep ahead, toss diced avocado with lemon juice and a tiny pinch of salt, then store tightly covered. For the rest, you can prep and portion the grains, tuna, and chopped veggies up to 3 days in advance.

Store components separately in airtight containers. Keep the dressing in a small jar and the nuts or seeds in a dry container so they stay crunchy.

Assemble the bowl the morning of, or bring the parts and build at your desk in two minutes.

Benefits of This Recipe

• High-protein and filling: Tuna provides lean protein; avocado adds satisfying healthy fats.
• Balanced nutrition: Grains add fiber and steady energy; veggies bring vitamins, minerals, and hydration.
• Budget-friendly: Canned tuna and pantry staples keep costs down without sacrificing nutrition.
• Quick and flexible: Works with different grains, greens, and add-ins based on what you have.
• Great for meal prep: Components store well and assemble in minutes.

Pitfalls to Watch Out For

• Watery bowls: Wet veggies dilute flavor. Pat tomatoes and cucumber dry before assembling.
• Mushy texture: Overmixing tuna with avocado can make the bowl pasty. Keep them in separate chunks.
• Bland dressing: Under-seasoning is common.

  Taste and adjust salt, lemon, and mustard until it pops.

• Fishy taste: Use quality tuna and drain well. A squeeze of lemon and fresh herbs cuts any strong flavor.
• Soggy greens: Don’t dress too far ahead. Add dressing right before eating for the best texture.

Variations You Can Try

• Mediterranean: Add olives, roasted red peppers, and swap dill or parsley as the herb.

  Use feta and a sprinkle of oregano.

• Spicy Sriracha: Mix a little sriracha or chili crisp into the dressing. Add edamame and shredded carrots.
• Mexican-inspired: Use cilantro, corn, black beans, and a lime-cumin dressing. Finish with cotija cheese.
• No-grain, extra greens: Skip the grains and double the greens for a lighter, low-carb bowl.
• Alternative protein: Swap tuna for canned salmon, grilled chicken, or chickpeas for a vegetarian option.
• Creamier dressing: Stir in 1–2 tablespoons of Greek yogurt for a tangy, creamy finish.

FAQ

What kind of tuna is best?

Solid or chunk light tuna is budget-friendly and mild.

For a richer flavor and firmer texture, choose solid white albacore. Tuna packed in olive oil tastes luxurious; if using water-packed, add a touch more olive oil to the dressing.

Can I make this dairy-free?

Yes. Skip the cheese and ensure your dressing does not include yogurt.

The bowl will still be creamy thanks to the avocado.

How long will leftovers last?

Assembled bowls without avocado stay fresh for up to 3 days in the fridge. Add avocado and dressing just before eating for the best texture.

What if I don’t like raw onion?

Soak sliced red onion in cold water for 10 minutes to tame the bite, or swap for thinly sliced scallions or chives.

Can I use frozen or pre-cooked grains?

Absolutely. Pre-cooked packets or frozen grains save time.

Warm them briefly, then cool before assembling to avoid wilting the greens.

How do I keep avocado from browning?

Toss diced avocado with lemon juice and store tightly covered, pressing plastic wrap directly onto the surface. This slows oxidation for several hours.

Is there a good vegetarian substitute for tuna?

Chickpeas are a great swap. Lightly mash them with lemon, olive oil, salt, and pepper for a hearty, protein-rich base.

Can I pack this for a flight or long commute?

Yes.

Pack grains, tuna, and veggies in one container, nuts in another, and dressing in a small jar. Add avocado and dressing right before eating to keep everything fresh.
