Portable egg muffins loaded with feta, spinach, sun-dried tomatoes, and kalamata olives, like a Greek omelet you can grab and go.
These are the ultimate grab-and-go protein snack. Make a batch of 12 on Sunday, keep them in the fridge, and grab 3 whenever you need a quick protein hit. They reheat in 30 seconds in the microwave and taste like a Greek omelet in portable form. Each serving of 3 gives you about 20g of protein, mostly from the eggs and feta. No cooking required during the week, no dishes, no excuses about not having time to eat something with actual protein in it.
The Greek flavor profile here is what keeps me making these instead of plain egg muffins. The feta gets slightly melty and salty throughout, the spinach wilts down to almost nothing so you barely notice it but you're still getting your greens, the sun-dried tomatoes add this concentrated burst of sweetness, and the kalamata olives give you that briny punch. A little oregano ties it all together. It's a legitimately good-tasting snack, not one of those "eat it because it's healthy" situations.
The key to good egg muffins is not overfilling the tin. Fill each cup about three-quarters full. They puff up in the oven and then settle back down as they cool. Grease the tin well with olive oil or use silicone muffin liners, because egg sticks to everything. I've also learned to let them cool in the tin for a few minutes before popping them out. They hold up well in the fridge for 4-5 days, and you can even freeze them for up to a month. Throw three in a ziplock bag, toss it in your gym bag, and you've got a post-workout snack ready whenever you need it.
Standard egg muffins with just eggs deliver about 12-13g protein per 3-muffin serving. We added a generous amount of crumbled feta cheese throughout the batter, boosting each serving to 20g protein while adding the salty, tangy flavor that makes these taste like a real Greek omelet.
