Prep the chicken: If using breasts, slice them in half horizontally to make cutlets, or pound to an even 1/2-inch thickness.
This helps the chicken cook quickly and evenly.
Mix the marinade: In a bowl, whisk olive oil, lemon zest, lemon juice, garlic, rosemary, thyme, oregano, honey (if using), salt, pepper, and red pepper flakes.
Marinate: Add the chicken and toss to coat. Marinate at least 20 minutes at room temp, or up to 6 hours in the fridge. Longer than that can start to change the texture because of the lemon.
Preheat and prep sides: Heat the oven to 425°F (220°C).
Toss potatoes with olive oil, salt, and pepper. Spread on a sheet pan. Roast 20 minutes, then add broccoli/green beans on the same pan with a little oil, salt, and pepper.
Roast another 12–15 minutes until tender and golden.
Cook the chicken: Heat a large skillet over medium-high. Add a light drizzle of oil. Shake off excess marinade and cook chicken 3–5 minutes per side, depending on thickness, until browned and the internal temperature reaches 165°F (74°C).
Rest and slice: Let the chicken rest 5 minutes.
Slice against the grain into strips or leave whole if you prefer.
Portion into containers: Divide chicken, roasted veggies, and potatoes/rice/quinoa into 4–5 containers. Add a small lemon wedge if you like fresh zing at reheat.
Finish with herbs: Sprinkle with chopped parsley for a fresh look and taste.
