Combine meat, bread crumbs, egg and salt; mix lightly. Shape into meatballs, brown in small amount of oil on all sides in large skillet. Drain. Add water, rice, carrots, green pepper and onion. Place in casserole dish and bake at 350 degrees till carrots are done about 35 to 45 minutes. Add cheese and heat until cheese melts. I sometime sadd a envelope of beefy onion soup mix for extra flavor.
