Instructions

1. Step 1: Preheat oven to 400°F. On a parchment-lined baking sheet, place 1 cup shredded sharp cheddar cheese in four 1/4 cup mounds. Flatten each mound into a 4-inch circle and bake for 5-7 minutes until bubbly and golden around the edges. Immediately drape each cheese circle over the back of a wooden spoon handle to shape taco shells and let cool.
2. Step 2: Meanwhile, heat 1 tbsp olive oil in a large skillet over medium heat. Add 1 lb ground beef, 1 tbsp chili powder, 1 tsp ground cumin, 1/2 tsp garlic powder, 1/2 tsp onion powder, 1/2 tsp salt, and 1/2 tsp black pepper. Cook, breaking up meat, for 8-10 minutes until browned and cooked through.
3. Step 3: To assemble, fill each cheese shell with 1/4 of the cooked beef mixture, 1/4 cup shredded lettuce, 1/4 sliced avocado, and 2 tbsp sour cream.
4. Step 4: Serve immediately to enjoy the crunchy shells with creamy and savory fillings.
