This Mediterranean Protein Frittata is my go-to when I need a serious morning energy boost without any gluten. By combining whole eggs with extra egg whites and lean turkey sausage, we're hitting those high-protein goals while keeping things light and flavorful. It’s a rustic, one-pan wonder that looks as good as it tastes and fills the kitchen with a wonderful savory aroma.

What I love most about this dish is how the salty tang of feta pairs with the earthy spinach and savory sausage. It's incredibly versatile—you can slice it up for a quick weekday grab-and-go meal or serve it straight from the skillet for a lazy Sunday brunch with friends. Plus, it stays moist and delicious even when reheated, making it a champion of healthy meal prep.

Tips & Notes

  • Make sure your skillet is oven-safe; cast iron or stainless steel works best for this recipe.
  • If you're meal prepping, slice the cooled frittata into wedges and store in airtight containers for up to 4 days.
  • To make it even higher in protein, you can swap the whole eggs for more egg whites, but the yolks add a nice richness.
