Prep the chicken: Pat the chicken dry. If the breasts are thick, slice them horizontally to create even cutlets.
This helps them cook quickly and stay tender.
Mix the seasoning: In a small bowl, stir together smoked paprika, garlic powder, onion powder, salt, and pepper. Rub this evenly over the chicken.
Make a quick marinade: In a separate bowl, combine BBQ sauce with olive oil and apple cider vinegar. Add honey if your sauce is very tangy or if you prefer a touch of sweetness.
Reserve 1/4 cup of this mixture for basting at the end.
Marinate: Add the seasoned chicken to the marinade, toss to coat, and chill for 20–30 minutes while you prep the sides. Longer is fine, but not required.
Prep the sides: Preheat the oven to 425°F (220°C). Dice sweet potatoes into 1/2-inch cubes.
On a large baking sheet, toss sweet potatoes with half the olive oil and a pinch of salt and pepper. On a second sheet, toss broccoli, bell pepper, and onion with the remaining oil, garlic powder, salt, and pepper.
Roast the veggies: Roast sweet potatoes for 25–30 minutes, stirring once. Roast the broccoli, peppers, and onion for 18–22 minutes, until crisp-tender with a little char.
If using cooked brown rice or quinoa instead of sweet potatoes, warm it near the end of cooking.
Cook the chicken (grill or oven): Grill or grill pan: Heat to medium-high and oil the grates. Grill chicken 4–6 minutes per side, depending on thickness, until internal temp hits 165°F (74°C). Brush with the reserved BBQ sauce during the last minute on each side.
Oven: Place chicken on a lined sheet at 425°F (220°C) for 14–18 minutes, flipping halfway.
Brush with reserved BBQ sauce in the last 3–4 minutes.
Rest and slice: Let the chicken rest for 5 minutes. Slice against the grain into strips or cubes. This keeps it juicy and easy to portion.
Assemble the meals: Divide the chicken among 4–5 containers.
Add a scoop of sweet potatoes or brown rice/quinoa and a generous serving of roasted vegetables. Garnish with chopped parsley or green onions if you like. Add a lemon wedge to each container for a fresh squeeze at mealtime.
Cool before sealing: Let everything cool to room temperature for 15–20 minutes, then seal the containers and refrigerate.
