01 - Preheat oven to 375°F (190°C). Lightly grease a 6-cup muffin tin with nonstick cooking spray or a thin layer of oil.
02 - Microwave tortillas for 15 to 20 seconds until soft. Press each tortilla gently into a muffin cup, forming an even shell by pleating edges as needed.
03 - In a medium mixing bowl, whisk together eggs, milk, salt, and black pepper until fully blended.
04 - Distribute crumbled bacon and half the shredded cheddar cheese evenly among the six tortilla shells.
05 - Pour the egg mixture into the tortilla shells, filling each cup nearly to the top without overfilling.
06 - Sprinkle remaining cheddar cheese and chopped green onions over each cup.
07 - Bake for 18 to 20 minutes or until eggs are set and tortillas turn golden and crisp.
08 - Let the cups cool in the tin for 2 to 3 minutes. Carefully lift each cup out. Garnish with chopped cilantro and serve with salsa or hot sauce as desired.
