1. In a mixing bowl, whisk the eggs together with the milk, salt, and pepper until well combined. Melt the butter in a skillet over medium heat, then pour in the egg mixture. Cook, stirring occasionally, until the eggs are softly scrambled and just set.

2. Lay out the flour tortillas on a clean work surface. Evenly distribute the scrambled eggs, crumbled turkey bacon, diced avocado, and shredded cheddar cheese among the tortillas.

3. Carefully roll each tortilla tightly, like a burrito, ensuring all the fillings are securely tucked inside. Heat a skillet over medium heat and toast the roll-ups, seam-side down, until golden brown and crispy on both sides.

4. Slice the Breakfast Roll-Ups in half diagonally and serve them warm. They make a delicious and portable breakfast that can be enjoyed on the go or at the table. Consider offering your guests a selection of sauces or toppings, such as salsa, guacamole, or hot sauce, to customize their roll-ups to their liking.
