Prep the grill or pan: Heat an outdoor grill, grill pan, or large skillet over medium-high.
Lightly oil the grates or pan so the vegetables don’t stick.
Season the vegetables: In a bowl, toss zucchini, eggplant, bell pepper, and red onion with olive oil, smoked paprika, cumin, oregano, garlic powder, salt, and pepper. Coat evenly.
Grill to tender-crisp: Place the vegetables on the hot surface. Cook 3–4 minutes per side until charred in spots and tender but not mushy.
Remove and let them cool slightly.
Add brightness: Squeeze lemon juice over the warm grilled veggies. This wakes up the flavors and balances the smoky notes.
Warm the tortillas (optional but recommended): Briefly warm each tortilla on the grill or in a dry pan for 15–20 seconds per side. Warm tortillas are more pliable and less likely to tear.
Spread the hummus: Lay a tortilla on a board.
Spread 2–3 tablespoons of hummus across the center, leaving space at the edges for rolling.
Layer the fillings: Add a handful of spinach, a few slices of cucumber, and a generous portion of grilled vegetables. If using, sprinkle on feta, olives, or herbs.
Roll it up: Fold the sides inward, then roll from the bottom up, keeping the filling snug. If the wrap seems loose, secure it with a toothpick or wrap it in parchment.
Serve or sear: Eat as is, or return the wrapped tortilla to the pan for 1–2 minutes per side to seal and crisp the exterior slightly.
Finish and enjoy: Cut in half.
Add a squeeze of lemon or a drizzle of tahini if you like. Serve with extra greens or a simple side salad.
