These egg white muffins with spinach and feta are a quick, protein-packed, and low-calorie breakfast option perfect for meal prep and maintaining a calorie deficit.
Do not overbeat the egg whites to avoid rubbery muffins. Pat spinach dry to reduce moisture and keep muffins from becoming soggy. Gently fold ingredients to preserve airiness. Muffins keep well refrigerated up to 5 days and freeze well. Reheat in toaster or conventional oven for best texture.
