Preheat oven to 350 F.

Grease a 9x18 casserole dish with butter.

In a large pan or skillet, spray avocado oil and cook at medium heat. Add the garlic and cook for 2 minutes. Add the bell peppers and green onion until the bell peppers are cooked thoroughly. (approx. 8 minutes)

Add the spinach and stir with a wooden spoon until its wilted (approx. 1-2 minutes). Turn off and set aside for cooling.

In a medium sized mixing bowl add the eggs, whole milk and salt. Also sprinkle black pepper and hot sauce as preferred. With a whisk, mix until egg yolks and egg whites are blended.

To this mixture, fold in half of the feta cheese and cooled veggies and combine well.

Pour the mixture evenly into the buttered casserole dish and add the remaining feta cheese.

Baked for approx. 25 minutes or until the eggs are puffy and cooked. The center should only jiggle slightly. To check, insert a fork or toothpick halfway in the center; it should come out clean.

Take out of the oven and let cool over a cooling rack.

Cut out slices and serve with your favorite topping; hot sauce, more feta cheese, or avocado. Yum! Enjoy!
