Preheat oven to 325ºF.

In an oven-safe skillet, heat butter medium heat. Add green onions, green chiles, and saute until green onions are softened (1-2 minute). Add spinach and stir and continue to cook until wilted, about 3-4 minutes.

Add salt and pepper to taste, keeping in mind that the cheese will add saltiness.

Pour in egg whites, and cottage cheese, stirring to combine. You can whisk these together in a bowl first.

Move to preheated oven and bake for 15 minutes or until eggs are set. Cool slightly before slicing into wedges and serving.
