Mexican stuffed shells is an old classic Recipe redesigned to maximize great taste. The way to make this the best is to use 85% ground beef and generic fried onions. French's quality has gone downhill recently. You might wonder we have this recipe that is missing noodles. Noodles and shells are very similar as far as my 4 year old is concerned and its a a meal that the whole family, including picky young kids, enjoy. This dish is also known as shell stuff and is about the most popular thing I can make.
