Prep the chicken: Slice breasts into 1/2-inch-thick strips for quick, even cooking. Pat dry with paper towels so the coating sticks.
Set up breading station: In one shallow bowl, beat the eggs with a pinch of salt.
In another, combine panko, Parmesan, paprika, garlic powder, onion powder, salt, and pepper.
Coat the chicken: Dip each strip into egg, shake off excess, then press into the panko mix until well coated. Place on a parchment-lined sheet. Lightly mist with cooking spray for extra crispness.
Cook the chicken: Bake at 425°F (220°C) for 12–15 minutes, flipping once, until golden and cooked through (internal temp 165°F/74°C).
For an air fryer, cook at 390°F (200°C) for 8–10 minutes, shaking halfway.
Make the sauce: Stir together Greek yogurt, olive oil, lemon juice, Dijon, and grated garlic. Season with salt and pepper. Adjust thickness with a splash of water if needed.
Warm the tortillas: Warm each wrap in a dry skillet for 15–20 seconds per side or microwave for 10–15 seconds so they’re flexible.
Assemble: Spread 1–2 tablespoons of sauce on each tortilla.
Layer greens, cucumbers, tomatoes, a few onion slices, and avocado if using. Top with crispy chicken.
Wrap it up: Fold the sides inward, then roll tightly from the bottom up. Slice in half if serving right away.
Finish with extras: Add fresh herbs, a squeeze of lemon, or a drizzle of hot sauce for a final pop.
