This 5-Ingredient Meal Prep Egg White Frittata is the perfect high protein meal prep breakfast, and it only has 181 calories per serving!
Step 1 Preheat oven to 400 F. Grease a large shallow round baking dish/cake pan with olive oil, making sure to grease the sides well.
Step 2 Add remaining ingredients, stirring well and gently with a fork.
Step 3 Place baking dish on top of a baking sheet lined with parchment paper just in case a bit of the oil rises above the egg white mixture (optional, but I do this to avoid grease dripping down into the oven as the egg whites rise and cook).
Step 4 Bake in the oven for 30-35 minutes until egg whites are firmly set.
Step 5 Remove from oven and slice into 4-5 pieces when cooled. Congrats, you've got breakfast ready for the week!
