Fluff with a fork. Stir in lime juice, cilantro, and a pinch of salt.
In a bowl, combine chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, salt, and pepper.

Heat a large skillet over medium-high. Add chicken in a single layer. Sear 4–6 minutes per side until browned and cooked through (165°F). Don’t overcrowd; work in batches for better browning.
Transfer to a cutting board. Rest 5 minutes, then slice or cube. Squeeze remaining lime over the top.
Warm beans and corn in a small saucepan with a splash of water and a pinch of salt, or microwave until hot.
Dice bell pepper, slice onion, halve tomatoes, and prep avocado right before serving to keep it fresh.
Add a scoop of rice to each bowl.
