Heat the olive oil in a large nonstick skillet over medium-high heat.
Add the diced onion and red bell pepper and sauté until softened, about 4 minutes.
Add the ground turkey and minced garlic to the skillet; season with cumin, chili powder, salt, black pepper, onion powder, and dried oregano.
Cook, breaking the turkey into crumbles, until browned and cooked through, about 5–7 minutes.
Stir in the cauliflower rice, drained black beans, enchilada sauce, corn, and salsa. Bring to a gentle simmer and cook for 5 minutes to blend flavors.
Gently fold in the tortilla strips, then sprinkle the shredded cheese evenly over the top.
Cover the skillet and cook off heat for 2–3 minutes until the cheese is melted, or cover over low heat briefly until melted.
Remove from heat, garnish with chopped cilantro and optional avocado and sliced jalapeños, and serve warm.
