1½ teaspoons freshly ground black pepper
12 tortillas
6 leaves Boston lettuce, torn in half
2 tomatoes, thickly sliced
1 avocado, thickly sliced
Lime slices, as needed for serving
Preheat the oven to 375°F. Line a baking sheet with aluminum foil. Arrange the bacon in an even layer on the baking sheet and sprinkle evenly with black pepper. Bake until evenly brown and crispy, 14 to 16 minutes. When the bacon is cool enough to handle, break each slice into 2 or 3 pieces. While the bacon cooks, heat a large skillet over medium heat. Working in batches, add 2 or 3 tortillas to the pan and heat until lightly browned on each side, 1 minute per side. Repeat until all tortillas are toasted. To serve, place 1 piece of lettuce, 1 or 2 pieces of tomato, 2 slices of avocado and 3 pieces of bacon on top of each tortilla. Serve immediately, with limes for squeezing.
