Looking for a grilled cheese spin that actually satisfies you through the afternoon This spinach and feta protein grilled cheese checks every box with its creamy filling packed with egg whites and tangy feta snuggled between crisp buttered bread I love it for lunch when I want something hearty but not heavy and it comes together in less than twenty minutes
I discovered this combination while trying to add more protein to my favorite comfort food and now it is a lunchtime staple even my picky eater requests it
Ingredients
- Whole wheat bread: needed for hearty texture and fiber aim for a dense bakery loaf for best results
- Egg whites: main source of protein here use fresh eggs or pasteurized pourable whites
- Fresh spinach: gives earthiness and adds vitamins always choose firm bright leaves
- Low fat feta: provides a creamy tang and lowers the calorie count opt for feta that is crumbly and moist
- Butter: delivers that iconic golden crunch look for real butter not spread for flavor and browning
Instructions
- Prepare the Filling:
- Crack egg whites into a small bowl and whisk until slightly foamy Fold in chopped spinach making sure the greens are completely coated by the eggs
- Scramble the Eggs:
- Heat a nonstick pan over medium low and add a light spray of oil or a dab of butter Scramble the egg white spinach mixture slowly stirring constantly until eggs are set and spinach is wilted about two to three minutes Transfer to a plate
- Assemble the Sandwich:
- Lay out bread slices Spread half the feta onto two bread pieces Spoon half the egg spinach mixture over feta Crumble the remaining feta on top Top each with a second bread slice to create two full sandwiches
- Butter and Preheat:
- Spread a thin layer of butter on the outer surfaces of each sandwich Heat a clean nonstick pan over medium
- Grill to Perfection:
- Place sandwiches butter side down in the skillet Cook for three to four minutes pressing gently Flip and continue grilling for another three to four minutes until both sides are crisp and golden Remove to a cutting board and let cool for one minute so filling sets slightly Slice and serve

For me the feta truly makes this sandwich It reminds me of family picnics when we would crumble feta over everything And I swear by using a hearty whole wheat loaf for a flavor that holds up to all that filling
Storage Tips
Wrap leftovers tightly in foil and refrigerate for up to two days Reheat in a toaster oven to restore crispness Avoid microwaving as that softens the bread
