The joys of a single pot recipe are hard to summarize. Well, thats not quite true: the words one-pot casserole make most of us very happy. This recipe turns super-convenient and frozen meatballs into a creamy, slightly cheese main dish, complete with the vegetables built right in. You could use other vegetables, such as broccoli or asparagus in place of the broccoli rabe if you like, and keep changing this dish up with the seasons. Another way to vary things up is to experiment with different flavors of frozen meatballs. A bag or two of meatballs in the freezer has saved dinner many a time. This dish was almost risotto-like, though it uses rice-shaped orzo pasta instead of rice, and involves with much less stirring. Even though this recipe says serves 8, my family of 4 did some pretty serious damage to the casserolebut there were thankfully still leftovers. There is more pasta than meatballs, though, since my kids went back into the pot, and plucked out the meatballs for their second servings
