Prep the chicken: Split the chicken breasts horizontally to create 4 thinner cutlets.
Pat dry. Season on both sides with salt, pepper, and garlic powder.
Sear the chicken: Heat the oil in a large skillet over medium-high heat. Add the chicken and cook 3–4 minutes per side until golden and the internal temperature reaches 165°F.
Transfer to a plate and tent loosely with foil.
Build the aromatics: Lower the heat to medium. If the pan is dry, add a small splash of oil. Add garlic and ginger.
Stir for 30–45 seconds until fragrant, being careful not to brown.
Make the peanut sauce: Whisk in peanut butter, soy sauce, fish sauce, chili paste, honey, rice vinegar, lime juice, and coconut milk (or broth). Stir until smooth. If it’s too thick, add a bit more coconut milk or water until it’s creamy and pourable.
Simmer and adjust: Let the sauce bubble gently for 2–3 minutes to thicken and meld.
Taste and adjust with more lime for brightness, soy for salt, or honey for balance. Stir in the sesame oil.
Optional veggies: If using quick-cooking vegetables, stir them into the sauce and cook 2–3 minutes until crisp-tender.
Finish the dish: Slice the chicken into strips and return to the pan, coating with sauce. Warm through for 1 minute.
Serve: Spoon over rice or noodles.
Top with chopped peanuts, cilantro, scallions, and extra lime wedges.
