Making Turkey Bacon Egg Cups involves just a few easy steps. Let’s break it down:

1. Preheat your Oven: Preheat your oven to 350°F (175°C).
2. Prepare Muffin Tin: Lightly grease a muffin tin with cooking spray or olive oil to ensure the egg cups don’t stick.
3. Cook Turkey Bacon: In a skillet, cook the turkey bacon over medium heat until crispy. Once cooked, chop the bacon into small pieces.
4. Prepare Egg Mixture: In a bowl, whisk together the eggs and milk. Add salt and pepper to taste, mixing until well combined.
5. Add Vegetables: Stir in the chopped spinach, diced bell pepper, cooked turkey bacon, and cheese if using. Mix thoroughly.
6. Fill Muffin Cups: Pour the egg mixture evenly into each muffin cup, filling them about 2/3 full to allow for rising.
7. Bake: Place the muffin tin in the oven and bake for 15-20 minutes, or until the eggs are set and the tops are slightly golden.
8. Cool and Remove: Allow the egg cups to cool for a few minutes before gently removing them from the muffin tray.
9. Serve: Enjoy them warm or allow them to cool completely before storing.
