A light, fluffy, and healthy egg white frittata with fresh spinach and tangy feta cheese, perfect for a quick and satisfying breakfast for two.
Use gentle folding to preserve airiness in egg whites. Avoid high heat on stovetop to prevent browning. If no oven-safe skillet, finish cooking under broiler in a baking dish. For dairy-free, omit or substitute feta with vegan cheese. Leftovers store up to 2 days refrigerated or freeze for up to 1 month.
