My mom first made a version of this recipe several years ago to shake up our Christmas morning menu and it has been a holiday breakfast staple ever since! Using classic TexMex flavors and ingredients, this breakfast casserole comes together in a snap and can easily be jazzed up with fun toppings such as hot sauce, salsa, sour cream, cilantro and lime. Add it to your holiday breakfast repertoire asap! I can promise you won't regret it
