Rinse the brown rice under cold water. Add to a pot with broth (or water) and a pinch of salt. Bring to a boil, reduce to low, cover, and simmer until tender (about 35–40 minutes). Rest 10 minutes, then fluff. Stir in lime zest, half the lime juice, and cilantro.
In a bowl, combine olive oil, chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, pepper, and chipotle (if using). Toss chicken to coat. Let sit 15–30 minutes (or up to 8 hours in the fridge).
Heat a large skillet over medium-high. Add a drizzle of oil and cook chicken 4–6 minutes, stirring, until browned and cooked through. Squeeze in a little lime juice at the end for extra pop.
If using beans, warm a skillet with olive oil over medium heat. Add garlic for 30 seconds, then cumin, oregano, chili powder. Stir in beans, a splash of water or broth, and a pinch of salt. Simmer 3–5 minutes until hot and flavorful.
Stir together tomatoes, red onion, jalapeño, cilantro, lime juice, and salt. Taste and tweak. If your tomatoes aren't amazing, add a pinch of sugar. No shame.
Slice avocado, chop peppers, thaw corn, shred greens, and set out cheese, yogurt, and hot sauce. This is your garnish runway.
Add a scoop of cilantro-lime brown rice. Top with chicken or beans (or both), corn, peppers, greens, salsa, and avocado. Finish with yogurt, cheese, hot sauce, and a lime squeeze.
If you like warmth without wilting everything, build the hot layers first (rice + protein + beans), then add cold toppings right before eating.
