Cook the grain: Prepare brown rice or quinoa according to package instructions.
Fluff and set aside.
Preheat and prep: Heat oven to 425°F (220°C). Line a baking sheet with parchment for easy cleanup.
Season the chicken: Pat chicken dry. Toss with salt, pepper, garlic powder, onion powder, and a drizzle of olive oil if baking or searing.
Roast or grill the chicken: Place chicken on the sheet pan.
Bake 18–22 minutes, until the thickest piece hits 165°F (74°C). Rest 5 minutes. For extra char, broil 1–2 minutes at the end.
You can also grill 6–7 minutes per side.
Roast the veggies: On a second pan (or the same pan if there’s room), toss broccoli, bell pepper, and carrots with olive oil, salt, and pepper. Roast 15–18 minutes until crisp-tender with some browning.
Make the buffalo sauce: In a small bowl, mix hot sauce, melted butter, honey, and Worcestershire. Adjust sweetness or heat to taste.
Slice or shred the chicken: Cut into strips or shred with two forks.
Toss with the buffalo sauce until coated. For saucier chicken, reserve a little extra to drizzle when serving.
Whisk the protein ranch: Combine Greek yogurt, light mayo, lemon juice, dill, parsley, garlic powder, salt, and pepper. Thin with a splash of water or milk if needed.
Taste and adjust acidity or salt.
Assemble the bowls: Divide rice or quinoa into 4 meal-prep containers. Add roasted veggies. Top with buffalo chicken.
Finish with a drizzle of protein ranch. Add optional blue cheese, green onions, and celery if you like.
Cool before sealing: Let containers cool uncovered for 15–20 minutes so steam doesn’t make them soggy. Then seal and store.
