Preheat your oven to 375°F (190°C).
Grease the muffin pan with extra-virgin olive oil.
Dice the red bell peppers and chop the scallions.
In a large mixing bowl, crack the eggs and add the grated garlic, sea salt, and black pepper. Whisk until combined.
In a separate bowl, combine the flour and baking powder. Stir until mixed, then fold into the egg mixture.
Fold in the diced red bell peppers, chopped scallions, and crumbled feta cheese.
Pour the mixture into the greased muffin cups, filling each about ¾ full.
Bake for 20-25 minutes or until set and lightly golden. A toothpick should come out clean.
Let cool in the pan for 5 minutes before transferring to a wire rack.
