Quick Egg Muffins with Spinach and Feta

6 large eggs
1/4 cup milk (or dairy-free alternative like almond or oat milk)
1 cup fresh spinach, chopped
1/3 cup crumbled feta cheese
Salt and black pepper, to taste
Optional: diced onions, cherry tomatoes, or herbs (like dill or parsley)
Non-stick spray or muffin liners

Preheat Oven:
Preheat your oven to 350°F (175°C). Lightly grease a 6-cup muffin tin or line with silicone or paper liners.
Whisk Eggs:
In a medium bowl, whisk together the eggs and milk until well combined. Season with a pinch of salt and pepper.
Add Fillings:
Stir in the chopped spinach and crumbled feta. If using optional ingredients like chopped onions or herbs, mix them in now.
Pour Into Muffin Tin:
Evenly pour the egg mixture into the prepared muffin cups, filling each about 3/4 full.
Bake:
Bake for 18–22 minutes, or until the egg muffins are set in the center and lightly golden on top.
Cool & Serve:
Let them cool for a few minutes before removing from the tin. Serve warm or let them cool completely and store in the fridge.

Refrigerate: Store in an airtight container for up to 4–5 days.
Freeze: Wrap individually and freeze for up to 2 months. Reheat in microwave or oven.
