3. Whisk the Eggs: In a mixing bowl, crack the eggs and whisk them until well combined.
4. Add Vegetables: Stir in the chopped spinach, diced bell peppers, diced onion, and any other vegetables you choose.
5. Incorporate Optional Ingredients: If using, add the chopped ham or bacon, shredded cheese, salt, pepper, and garlic powder to the egg mixture. Mix well.
6. Distribute the Mixture: Pour the egg mixture evenly into each muffin cup, filling them about 3/4 full.
7. 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.
