Preheat oven to 400F and line large baking try with parchment or aluminum foil and lightly spray with oil.
Brown meat over medium-high heat. Once meat is cooked add Taco Seasoning and water per packet's instructions.
While meat is browning, seed and cut peppers in half. Arrange on the tray so that they are close together.
Next, fill each pepper with cooked taco meat and top with shredded cheese.
Bake in the oven for 8-10 minutes, or until cheese is melted.
Remove from oven and top with your favorite toppings; sour cream, jalapenos, salsa, onion, cilantro or hot sauce.
