Creating Mini Toca Boca Egg Muffins is straightforward if you follow these steps:

1. Preheat your oven to 375°F (190°C) and prepare a muffin tin by spraying it lightly with cooking spray or lining it with muffin liners.
2. Whisk together the eggs and milk in a large bowl until well combined.
3. Add the cheese to the egg mixture, stirring to distribute evenly.
4. Incorporate the diced vegetables into the mixture, ensuring they are evenly mixed.
5. Season the mixture with salt, pepper, garlic powder, and onion powder if using. Mix well.
6. Pour the egg mixture evenly into each muffin cup, filling them about ¾ full.
7. Bake in the preheated oven for 15-20 minutes or until the muffins are puffed up and a toothpick inserted into the center comes out clean.
8. Remove from the oven and let the muffins cool in the tin for a few minutes before transferring them to a wire rack.
9. Store any leftovers in an airtight container in the refrigerator for up to 5 days or freeze for longer storage.
