Grease a 9x9-inch baking dish. Combine the shredded squash, thickened cheese sauce, roasted broccoli, and frozen peas in a large
mixing bowl and pour the mixture into your prepared baking dish. Season with
ground pepper and
red chili flakes and bake it in the already preheated oven for about 20 minutes. Then switch the oven to broil and broil for 5 more minutes.
