Season the chicken. Add the diced chicken to a bowl. Drizzle with olive oil and season with chili powder, smoked paprika, garlic powder, onion powder, cumin, salt, pepper and lime juice. Toss well to coat.
Cook the chicken. Heat a large nonstick skillet over medium-high heat. Cook the chicken for 6 to 8 minutes, stirring occasionally, until golden and cooked through. Remove from heat.
Mix the creamy salsa dressing. In a small bowl, whisk together salsa, Greek yogurt, lime juice and a pinch of salt. Adjust thickness with a splash of water if you prefer it thinner.
Build your burrito bowls. Divide the rice (or quinoa) between two bowls. Add the cooked chicken, black beans, corn, cherry tomatoes, and shredded lettuce. Top with avocado slices and a drizzle of creamy salsa dressing. Sprinkle cilantro if you like.
Serve. Enjoy immediately, or pack into airtight containers for meal prep (keeps 2–3 days in the fridge).
