Cook your base: Prepare brown rice, quinoa, farro, or cauliflower rice according to package directions.
Fluff and set aside. For extra flavor, add a pinch of salt and a squeeze of lime while it rests.
Preheat and prep: Heat the oven to 425°F (220°C). Line two baking sheets with parchment for easy cleanup.
Pat the chicken dry with paper towels.
Season the chicken: In a bowl, toss chicken with 1–2 tablespoons olive oil, 2 tablespoons ranch seasoning, and a pinch of black pepper. If your ranch mix is low-sodium, add 1/2 teaspoon salt. Optional: add 1/2 teaspoon garlic powder and 1/2 teaspoon smoked paprika.
Prep the veggies: Toss broccoli, bell pepper, and red onion with 1 tablespoon olive oil, salt, and pepper.
Spread on one baking sheet. Add corn and cherry tomatoes in a separate section or on a second sheet to prevent sogginess.
Roast everything: Place chicken on the second sheet. Roast chicken and veggies for 16–22 minutes, flipping chicken halfway.
Veggies should be tender and lightly charred; chicken should reach an internal temperature of 165°F (74°C).
Rest and slice: Let chicken rest 5 minutes, then slice or dice into bite-sized pieces. This keeps it juicy and easy to eat in bowls.
Make the Greek yogurt ranch: Stir Greek yogurt, 1 tablespoon ranch seasoning, lemon juice, and 1 tablespoon water or milk. Adjust thickness with more liquid.
Taste and add salt or pepper if needed.
Warm the beans (optional): If using beans, warm in a small skillet with a splash of water, salt, and pepper for 2–3 minutes, or leave them cold for a quick protein add-in.
Assemble: Divide base among bowls. Top with chicken, roasted veggies, beans, and corn. Add cherry tomatoes last for freshness.
Spoon on the yogurt ranch and finish with chopped cilantro or parsley and avocado if using. Serve with lime wedges.
Adjust and enjoy: Taste and add a pinch of salt, extra ranch drizzle, or hot sauce to fit your preferences.
