These easy muffin tin frittata bites combine salty feta, tender spinach, and fluffy eggs for a quick, protein-packed breakfast or snack that’s perfect for busy mornings or casual brunches.
Sauté spinach and onions first to remove excess moisture and prevent soggy frittatas. Let eggs come to room temperature before mixing for better fluffiness. Cover with foil if tops brown too quickly. These freeze well and reheat nicely.
