1. Preheat your oven to 350°F (175°C) and grease a muffin tin with cooking spray or line with muffin liners.
2. Whisk the Eggs: In a large mixing bowl, crack the eggs and whisk them until well combined.
3. Add Milk: Pour in the milk and continue whisking until the mixture is smooth.
4. Combine Vegetables: Stir in the chopped bell peppers, spinach, onions, and any additional vegetables you desire.
5. Season the Mixture: Add salt, black pepper, garlic powder, and paprika. Stir well to ensure even flavor distribution.
6. Incorporate Cheese: Fold in the shredded cheese, mixing until everything is evenly combined.
7. Fill Muffin Tins: Pour the egg mixture evenly into each muffin cup, filling them about ¾ full.
8. Bake: Place the muffin tin in the preheated oven and bake for 20-25 minutes or until the muffins are set and lightly golden on top.
9. Cool: Once baked, remove them from the oven and let them cool in the tin for about 5 minutes.
