Spinach and Cheese Muffins

Preheat your oven to 180°C (350°F) and grease a muffin pan or line with paper liners.

In a large bowl, mix together the flour, baking powder, baking soda, and salt.

In another bowl, whisk the eggs, then add milk and olive oil, mixing until well combined.

Gradually add the wet ingredients to the dry ingredients, mixing gently until just combined.

Fold in the chopped spinach, onion, red bell pepper, shredded cheese, garlic powder, and black pepper until evenly distributed.

Spoon the mixture into the prepared muffin pan, filling each cup about three-quarters full.

Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted into the center comes out clean.

Let the muffins cool in the pan for 5 minutes before transferring to a wire rack to cool completely.
