For Bacon: Preheat the oven to 400℉ (200℃). Line a rimmed baking tray with foil and place a wire baking rack on top of the baking tray. Lay the bacon evenly across the baking rack, so that it is not overlapping. Bake for 15-18 minutes, or until crispy. Remove from the oven and transfer the bacon to a plate, lined with paper towels to cool. Once cool, crumble into bite-sized pieces.
For Sausage: Heat 1 teaspoon of oil in a large nonstick skillet over medium-high heat. Once the oil is heated, add in the sausage and cook until no longer pink, breaking it into small pieces as it browns.
For the Eggs: While the bacon or the sausage is cooking, whisk together 6 large eggs, ¼ cup milk , 2 tablespoons sour cream, ½ teaspoon kosher salt and ½ teaspoon pepper until well combined. Heat 1 tablespoon butter in a nonstick skillet over medium heat. Once the butter is melted, add the egg mixture to the pan. Use a spatula to whisk and scramble the eggs while they cook, until they are just cooked through, yet still soft.
Heat Tortillas: Remove the cooked eggs to a platter, wipe out the pan with a paper towel, and return to the heat. Warm 8 small flour tortillas one by one, over medium-high heat until just pliable–about 15 seconds per side.
Assemble Tacos: To assemble the tacos, top each tortilla with a scoop of scrambled eggs, bacon bits, shredded cheese, and sliced avocado. Garnish with sliced tomatoes, salsa, sour cream, and minced cilantro as desired. Serve immediately.

Notes
Meat: While I have included instructions on how to bake bacon and how to cook sausage, feel free to omit the meat OR replace sausage or bacon with cooked and crumbled chorizo, diced ham, or diced Canadian bacon. Cheese: Use any type of shredded or crumbled cheese you like. Cheddar, Colby, and Swiss are all great options. Tortillas: Use your corn or flour tortillas or hard taco shells for this recipe. I would recommend using a smaller soft taco-size tortilla for ease of eating.Storage: If you have any leftover scrambled eggs or breakfast meat, store them in separate air-tight containers in the refrigerator for up to 3 days. Warm and then use the components to assemble breakfast tacos as desired.
