Pound or slice the chicken: If the breasts are thick, slice them into cutlets or pound to an even 1/2-inch thickness. Even thickness = even cooking.
Pat dry and season: Blot the chicken dry with paper towels. Lightly season both sides with salt and pepper.
Preheat and prep: If baking, heat the oven to 425°F (220°C).
Line a sheet pan with parchment and brush with oil. If pan-frying, set a large skillet over medium heat and add a thin layer of oil.
Mix the crust: In a shallow bowl, combine panko, Parmesan, garlic powder, onion powder, smoked paprika, salt, and pepper. Stir well to evenly distribute the seasoning.
Make the egg wash: In another bowl, whisk eggs with Dijon until smooth.
Coat the chicken: Dip each piece in the egg wash, letting excess drip off.
Press firmly into the Parmesan-panko mixture to coat both sides. Pressing helps the crust adhere.
Cook the chicken (bake option): Arrange on the sheet pan and drizzle or mist lightly with oil. Bake 15–18 minutes, flipping once, until the crust is golden and the internal temperature reaches 165°F (74°C).
Cook the chicken (pan-fry option): Fry 3–4 minutes per side over medium to medium-high heat, adjusting heat as needed to avoid burning. Transfer to a rack to stay crisp.
Make the dressing: Zest the lemon, then juice it into a small bowl.
Whisk with extra-virgin olive oil, a pinch of salt, and pepper. Taste and adjust with more lemon or oil as needed.
Toss the greens: In a large bowl, combine greens and herbs. Drizzle with dressing and toss gently right before serving so the greens stay perky.
Plate and finish: Pile greens onto plates, top with chicken, and add optional extras like cherry tomatoes, shaved Parmesan, or a pinch of red pepper flakes.
Finish with a squeeze of fresh lemon for brightness.
