Pre heat oven to 375°

Crack the eggs into a medium sized mixing bowl and whisk well

Dice tomatoes and red onion, and chop the spinach then add to a large mixing bowl

To the mixing bowl with the tomatoes and onion, add whisked eggs, baby spinach, garlic powder, onion powder, salt, and pepper

Lightly grease a casserole dish (I like to use avocado oil spray) and pour mixture into dish

Bake uncovered for 40 minutes

Let cool then cut into equal squares and store in an air tight container in the refrigerator
