This is a recipe that I use to deal with leftover pork in roast, chop or pork loin form. It is very flexible in helping to use up other vegetables as well. You can even substitute the pork for leftover chicken too. A simple recipe that makes an easy meal. You can add diced mushrooms, partially cooked carrots, asparagus, peas and other vegetables that you wish to use. I've also sprinkled leftover bacon bits onto the casserole during the last five minutes of cooking. Adding a 1/2 package of onion soup mix to the soup mixture will also increase the flavour. If you want a thicker soup and are not adding the rice to the casserole dish, substitute the 5 ounces (1/2 the soup can) of milk with 8 to 10 ounces of sour cream. This alternative goes very well with egg-noodles rather than rice.
