Prepare a 12-cup muffin tin by coating each cup with cooking spray. In a large bowl, whisk together eggs, salt & pepper.
Transfer egg mixture to a 2 cup measuring cup, add water till you have 2 cups of liquid(if you have extra water, dont worry just dump it).
Mix mixture till it is all even.
Fill each muffin cup with egg mixture to no more than 3/4 full.
Bake for 15min, take out of oven and sprinkle with goat cheese, continue baking for another 5-10 till egg is set and the tops of the frittatas are starting to brown. Run a knife around the edge of each frittata and gently life them out. Serve Immediately.
