Instructions

1. Step 1: Preheat oven to 400°F. On a parchment-lined baking sheet, spread 1/4 cup shredded sharp cheddar cheese into 4 circles about 5 inches in diameter, spacing them apart.
2. Step 2: Bake cheese circles for 5-7 minutes until melted and edges are golden brown and crispy. Remove from oven and immediately drape each cheese circle over the side of an inverted bowl to form taco shell shapes. Let cool and harden.
3. Step 3: Heat 1 tbsp olive oil in a skillet over medium-high heat. Add 1 lb ground beef, 2 tbsp taco seasoning, 1 tsp salt, and 1/2 tsp black pepper. Cook, breaking up meat with a spoon, for 7-8 minutes until browned and cooked through.
4. Step 4: To assemble, fill each cheese shell with about 1/4 of the seasoned ground beef, 1/4 cup shredded romaine lettuce, 2-3 slices of 1 medium avocado, and a dollop of 2 tbsp sour cream.
