Preheat oven to 350 F and grease a muffin tin with cooking spray.
Add breakfast sausage (12 Oz) to a skillet and cook while breaking it up with the back of your spoon. Cook until the sausage is no longer pink.
Move to paper towel lined plate.
Carefully clean the skillet with a paper towel and add veggie oil (1 tablespoon).
Add chopped onion (1/2 cup) and chopped bell pepper (1/2) and saute until the onion is translucent.
Meanwhile, combine eggs (12 large in size), heavy cream (1/2 cup), salt (1/2 teaspoon), dash of pepper and low carb taco seasoning (1 tablespoon) in a bowl.
Stir in cheese (1/2 cup), sausage and veggies.
Pour mixture into prepared muffin tins.
Bake in the oven for 20-25 minutes, or until the center is set.
Serve warm and enjoy!
