Southwestern Spaghetti Casserole



This comforting pasta dish is very delicious,flavorful and satisfying.This dish can be vegetarian using mushrooms instead of meat or ground beef,chicken or turkey for meat lovers.If you’ll be using chicken broth,I highly recommend to make it from scratch.In my opinion it’s really more flavorful then store bought.
