Preheat your oven and spray the muffin tin generously. Chop spinach, sun-dried tomatoes, and basil so they fit nicely into the cups. I always make sure the tomatoes are drained well to avoid excess oil.
In a blender, combine eggs, cottage cheese, and sea salt. Pulse just until smooth; over-blending can make the bites rubbery. The batter should be creamy but not too frothy.
Gently fold in spinach, sun-dried tomatoes, and basil. Pour the mixture into the muffin cups about 80% full so they have room to rise without overflowing.
Place the muffin tin in the oven and bake for 20 minutes or until the bites are set and slightly golden. Let them cool for a few minutes before topping with feta and black pepper.
You can enjoy immediately or let the egg bites cool and store in the fridge or freezer for later. They’re perfect for grab-and-go breakfasts.
