Combine the chili powder, cumin and smoked paprika in a small bowl. Sprinkle half the seasoning onto the chicken breasts along with salt and pepper.
Heat the oil in a large skillet and cook the chicken breasts over medium heat until they are cooked through. Place the cooked chicken on a plate and set aside.
Add a little more oil to the skillet or spray with cooking spray if using a non-stick skillet.
Dump in the cauliflower rice, green onions, garlic, remaining spice mixture, salt and pepper. Sauté for 10-12 minutes or until the cauliflower is tender.
Add the salsa, black beans, green chiles and cilantro to the cauliflower rice and stir everything together until it’s heated through.
Nestle the chicken breasts into the cauliflower rice and top them with extra salsa and the shredded cheese.
Cover the skillet with a lid and heat until the cheese is melted. Serve topped with extra cilantro and green onions if desired.
