Prep the peppers: Heat the oven to 400°F (200°C). Slice peppers in half lengthwise, remove seeds and membranes, and place cut-side up in a baking dish.
Brush or spray lightly with oil and season with a pinch of salt.
Pre-bake: Roast peppers for 10–12 minutes to soften slightly. This helps them cook through without the filling drying out.
Sauté aromatics: While peppers bake, warm the oil in a large skillet over medium heat. Add onion and cook 3–4 minutes until softened.
Stir in the garlic and cook 30 seconds until fragrant.
Brown the turkey: Add ground turkey. Cook, breaking it up with a spatula, until no longer pink, about 5–7 minutes. If there’s excess moisture, let it cook off.
Season well: Stir in cumin, chili powder, smoked paprika, oregano, salt, and pepper.
Cook 1 minute to bloom the spices.
Add sauce and veggies: Pour in the enchilada sauce, green chiles, and riced cauliflower. Simmer 2–3 minutes until slightly thickened. Taste and adjust salt.
Finish the filling: Off the heat, stir in 1/2 cup shredded cheese, cilantro, and lime juice.
The cheese will melt and bind the mixture.
Stuff the peppers: Spoon the turkey filling evenly into the pre-baked pepper halves. Top with the remaining 1/2 cup cheese.
Bake: Return the dish to the oven and bake 12–15 minutes, until the peppers are tender and the cheese is melted and bubbling.
Garnish and serve: Let cool 5 minutes. Top with jalapeños, avocado, sour cream, and extra cilantro if you like.
Serve with lime wedges.
