Ingredients
Method
- Preheat oven to 375°F and spray a 12-cup muffin tin so the muffins pop out easily.
- Whisk eggs, milk, salt, pepper, and oregano in a large bowl until combined.
- Fold in chopped spinach and crumbled feta so everything is evenly mixed.
- Pour mixture into muffin cups about 3/4 full; they puff but don’t overflow.
- Bake 18–22 minutes until centers are set and tops are lightly golden.
- Cool 10 minutes, then remove and let fully cool before freezing in a single layer.
