Step 1:
Preheat your oven to 350°F.
Grease a 9×13 baking dish and set it aside.

Step 2:
In a large sauté pan, heat olive oil over medium-high heat for about 3 minutes.
Add the chopped onions and minced garlic and cook, stirring occasionally, until fragrant and softened.

Step 3:
Add the ground turkey (or beef) to the pan.
Cook for about 10 minutes, breaking it up with a spoon, until fully browned and no longer pink.

Step 4:
While the meat is cooking, prepare your peppers.
Slice them in half from top to bottom, remove the seeds and membranes, and place the pepper halves cut-side up in the greased baking dish.

Step 5:
Once the meat is browned, remove the pan from heat.
Stir in the tomato sauce, taco seasoning, black beans, corn, and cooked rice.
Mix well to combine everything into a hearty, flavorful filling.

Step 6:
Spoon about ¾ cup of filling into each pepper half, packing it down gently with the back of your spoon or your hand.

Step 7:
Sprinkle the tops generously with shredded cheddar cheese.

Step 8:
Bake the stuffed peppers uncovered in the preheated oven for 15-20 minutes.
The cheese should be melted and bubbling, and the peppers should be tender enough to pierce easily with a fork.

Step 9:
Remove from the oven and let cool slightly before serving.
Enjoy the gooey, savory goodness in every bite!
