Spray the muffin tin with cooking spray VERY WELL.
Crack eggs into a bowl and beat.
Add yogurt and salsa and stir to combine. (There might still be some small lumps of the yogurt. That is okay.)
Divide mixture evenly into a 12 muffin tin. The mixture will go almost to the top. I used a small (came with my silverware) soup ladle and 3 ladles was perfect for each muffin cup.
Bake approximately 30 minutes or until a knife inserted into the center of the cups comes out clean. Do not underbake as this makes them hard to get out of the muffin tin.
Allow egg bites to cool for about 10 minutes and then remove from muffin tin. Serve warm or allow to cool completely before storing in the fridge or freezer.
