Prep your base: Cook cauliflower rice, brown rice, or quinoa according to package directions. Fluff and set aside.
Season the chicken: Pat chicken dry.
Sprinkle with 1 teaspoon chili powder, 1 teaspoon cumin, 1/2 teaspoon smoked paprika, 1/2 teaspoon garlic powder, 1/2 teaspoon salt, and a few cracks of black pepper.
Sear the chicken: Heat 1 tablespoon oil in a large skillet over medium-high. Sear chicken 3–4 minutes per side until lightly browned.
Simmer in sauce: Reduce heat to medium-low. Pour in 2 cups enchilada sauce and 1/2 cup broth (if using).
Cover and simmer 10–12 minutes, or until the chicken is cooked through and shreds easily.
Sauté veggies: While chicken simmers, in a second skillet lightly spray with oil. Sauté onion and bell peppers 5–6 minutes until tender. Stir in corn and black beans to warm through.
Season with a pinch of salt and cumin.
Shred the chicken: Transfer cooked chicken to a board and shred with two forks. Return to the skillet and toss in the sauce. Let it simmer uncovered 2–3 minutes to thicken.
Build your bowls: Add your base to each bowl.
Top with saucy shredded chicken, the veggie-bean mix, and a small sprinkle of cheese if using.
Finish with fresh toppings: Add a spoonful of Greek yogurt, a squeeze of lime, chopped cilantro, and any extras like salsa, jalapeños, or avocado.
Taste and adjust: Add hot sauce or an extra pinch of salt, if needed. Serve warm.
