Preheat oven to 350 degrees and spray mini muffin pan with non-stick cooking spray.
Pour olive oil into a small skillet. Add peppers, onions and garlic and cook over medium heat for two minutes.
1/4 cup bell peppers, 1/4 cup purple onion, 1/2 tablespoon minced garlic, 1/2 tablespoon olive oil
Stir in spinach and cook for an additional minute.
1/2 cup spinach
Remove from heat. Add olives and mix well.
1/4 cup olives
Spoon vegetable mixture into each muffin tin.
Sprinkle feta cheese over the top of the veggies.
1/4 cup feta cheese
In a medium mixing bowl, whisk together eggs and milk. I used 1% milk.
3 large eggs, 1 1/2 tablespoon milk
Pour egg mixture over the veggies. I find it easiest to pour the eggs into the tins using a measuring cup.
Bake at 350 degrees for 20 minutes. Remove from oven and add salt and pepper to taste.
Salt & pepper to taste
Garnish with additional feta cheese and/or chopped parsley (optional)
Extra feta & chopped parsley for garnish
Let stand for five minutes and remove from muffin tins. Serve warm.
Notes
This recipe is made with a mini muffin pan, but you can easily make it with a regular size muffin pan. You will just get 6 large egg muffins instead of 12 small ones (or you can double the recipe to get 12).
For keto egg bites, you'll want to use heavy whipping cream instead of milk.
