Preheat your oven to 300°F (150°C).
Grease a muffin tin with cooking spray or olive oil.
In a blender, combine the eggs, cottage cheese, salt, and pepper. Blend until smooth.
Stir in the shredded cheese, diced peppers, and cooked bacon or sausage if using.
Pour the egg mixture evenly into the prepared muffin tin, filling each cup about 3/4 full.
Bake in the preheated oven for 25-30 minutes until the egg bites are set and slightly golden.
Remove from the oven and let them cool for a few minutes.
Gently run a knife around the edges to loosen the bites.
Carefully remove the egg bites from the muffin tin.
Serve warm, optionally topped with fresh herbs or your favorite sauce.
