Prep the chicken: Pat the chicken dry and slice thicker breasts in half horizontally for even cooking.
This helps keep it juicy and speeds things up.
Make the marinade: In a bowl, whisk together the reduced-sugar BBQ sauce, apple cider vinegar, smoked paprika, garlic powder, onion powder, chili powder, salt, and pepper.
Marinate: Toss the chicken in the marinade, coating well. Let it rest at least 20–30 minutes at room temp, or up to 8 hours in the fridge for deeper flavor.
Heat your cooking surface: Preheat the grill to medium-high, or set the oven to 425°F (220°C). If using a skillet, preheat over medium-high heat and lightly oil it.
Roast the veggies: On a sheet pan, toss broccoli, bell pepper, red onion, and zucchini with olive oil, salt, and pepper.
Roast for 18–22 minutes, stirring once, until tender with a bit of char.
Cook the chicken: Grill 4–6 minutes per side (depending on thickness), or bake at 425°F for 16–20 minutes. In a skillet, cook 4–5 minutes per side. Chicken is done at 165°F internal temperature.
Glaze at the end: Brush a little extra BBQ sauce on during the last 1–2 minutes to create a glossy finish without burning the sugars.
Rest and slice: Let the chicken rest 5 minutes before slicing. This keeps the juices in the meat.
Cook your starch: Prepare brown rice as directed, or quickly sauté cauliflower rice with a pinch of salt and a squeeze of lemon for freshness.
Assemble: Divide rice or cauliflower rice into containers, add roasted veggies, and top with sliced BBQ chicken.
Garnish with herbs and a lemon wedge if you like.
