Preheat oven to 350 degrees. In a 13x9 pan, melt the butter as the oven preheats. Thaw whichever veggie you are choosing and drain very well, squeezing out excess fluid.
In a large bowl, whisk egss thoroughly. Add the cottage cheese, flour, and shredded cheese. Mix very well. Add the veggies and pour in the melted butter. Mix again.
Pour into 13x9 pan and bake for 50-60 minutes. Edges should be golden and a knife inserted in the center comes out clean. Slice and serve! This can be made in 2 square pans. Serve one now and freeze one for later.
Variations: I have made this with browned, crumbled sausage and seeded chopped tomato in place of the veggies.
