Preheat and prep peppers: Heat your oven to 375°F (190°C). Slice the tops off the bell peppers and scoop out seeds and membranes.
If needed, trim the bottoms slightly so they stand upright without tipping.
Soften peppers (optional but helpful): Place peppers cut-side up in a baking dish. Add 1/2 cup broth to the bottom. Cover tightly with foil and bake for 10–12 minutes to soften.
Remove from oven and set aside. Keep the broth in the dish.
Sauté aromatics: Warm olive oil in a large skillet over medium heat. Add onion with a pinch of salt and cook 3–4 minutes until translucent.
Stir in garlic and cook 30 seconds until fragrant.
Cook the protein: Add ground turkey. Break it up with a spoon and cook until no longer pink, 5–7 minutes. Season with taco seasoning, salt, and pepper.
Add sauce and mix-ins: Stir in tomato sauce or salsa.
Fold in cooked brown rice, corn, and black beans. Simmer 2–3 minutes to thicken slightly. Taste and adjust seasoning.
Fill the peppers: Spoon the taco mixture into each pepper, packing it down gently.
Top each with a small handful of shredded cheese.
Bake: Return the baking dish to the oven, uncovered, and bake 15–18 minutes until the peppers are tender and the cheese is melted and bubbly.
Finish with freshness: Let cool for a few minutes. Sprinkle with cilantro and a squeeze of lime. Add any optional toppings you love.
Meal prep: Portion the peppers into meal prep containers (1–2 halves per serving).
Add a lime wedge and a small container of Greek yogurt on the side.
