Preheat the oven to 400ºF. Place the bacon on a rimmed baking sheet and bake for 15-20 minutes, or until crispy. Crumble the cooked bacon - set aside.
In a bowl, whisk together the eggs, milk, salt, and pepper.
Heat olive oil in a nonstick skillet over medium-low heat.
Pour in the eggs and cook for 10 seconds before flipping them with a rubber spatula. Continue cooking the eggs on medium-low, stirring every few seconds until they are soft and fluffy. Remove the pan from the heat.
Warm the tortillas in a greased skillet over medium heat - set them aside.
Assemble the breakfast tacos by dividing the scrambled eggs between the tortillas. Top with crumbled bacon, diced avocado, cheddar cheese, chopped parsley, and a squeeze of lime juice.
