Butterfly or pound the chicken: For even cooking, pound breasts to about 1/2-inch thickness or slice them into cutlets. This keeps them tender and reduces cook time.
Mix the marinade: In a large bowl, whisk olive oil, lemon zest, lemon juice, garlic, parsley, rosemary, thyme, smoked paprika, red pepper flakes, salt, pepper, and honey if using.
Marinate: Add chicken to the bowl and coat well. Cover and chill for at least 30 minutes, up to 6 hours.
Longer than that can make the texture mealy because of the acidity.
Prep the sides: While the chicken marinates, cook quinoa or rice and roast veggies. Toss vegetables with olive oil, salt, and pepper, and roast at 425°F (220°C) for 15–20 minutes until tender and lightly browned.
Choose your cooking method: For a skillet, heat a large pan over medium-high and add a light drizzle of oil. For the grill, preheat to medium-high and oil the grates.
For the oven, preheat to 425°F (220°C) and line a sheet pan.
Cook the chicken: Remove chicken from the marinade (let excess drip off). Skillet: Sear 4–6 minutes per side until golden and 165°F (74°C) inside.
Grill: 3–5 minutes per side for cutlets, depending on thickness.
Oven: Bake 12–16 minutes, broiling the last 1–2 minutes for color if needed.
Rest and slice: Let the chicken rest 5 minutes so the juices settle. Slice against the grain into strips.
Build your boxes: Divide quinoa or rice among 4 meal prep containers. Add a generous portion of roasted vegetables.
Top with sliced chicken and a squeeze of fresh lemon.
Finish with herbs: Sprinkle extra parsley or thyme over the top for a fresh pop before sealing.
