Cook the bacon first (any way you like). You can cook it in the oven or on a griddle or a pan on the stove. Example: Preheat oven to 400. Line a baking sheet with parchment paper. Lay bacon slices on parchment, trying not to let them touch. Bake at 400F for 20 min. Allow to cool slightly. Crumble.
Add eggs, salt, and pepper to a medium bowl. Beat with a whisk until well beaten.
Grease 12 small muffin cups/tins with coconut, avocado or olive oil and then divide the egg mixture evenly between all muffin cups.
Divide the bacon and red pepper (or other veggies) evenly between the muffins by sprinkling them into the egg mixture. Top evenly with shredded cheese.
Bake at 350 F for 20 minutes or until eggs are fully set.
