Sauté the shallots in melted butter until translucent and add red pepper flakes. Sauté for ~1 min (until fragrant) and add mushrooms. Sauté until mushrooms are tender, 5-10 min.
Brush a pie dish with melted butter and layer phyllo sheets, brushing butter between each layer. I used 4 sheets, but you could use more for a thicker crust.
In a large bowl, combine eggs, cottage cheese, salt, and Italian seasoning. Whisk until well combined.
Spread mushroom mixture on top of phyllo sheets and pour egg mixture on top. Use a vegetable peeler to shave zucchini on top of the egg mixture and top with tomatoes.
Bake at 350 for 30 min, cover with foil and bake for an additional 20 min, until the center is set.
I love using cottage cheese in a quiche because it gives it the creaminess that a traditional quiche would get from milk or cream, without extra fat. It will also increase the protein content just a bit!
Enjoy!
