These healthy veggie-packed egg white frittata muffins are a quick, nutritious, and easy meal prep breakfast option, packed with fresh vegetables and protein while being light on calories.
Whisk egg whites until frothy but not stiff to keep muffins light. Use olive oil spray or silicone liners to prevent sticking. Finely chop vegetables for even cooking. Cover with foil if muffins brown too fast. Prep veggies ahead to save time. For vegan option, omit cottage cheese and use flax or chia egg substitute with nutritional yeast.
