Soups, stew, chili, hash, over rice, spaghetti sauce, tacos, burritos, shepherd pie, pot pie, dirty rice, goulash - pretty much anywhere you would use ground or diced meat, but you get to skip the browning step. Suppose you could even use it instead of chipped beef in SOS, but I wouldn't!
Also really good in a sandwich or cracker spread - run it thru food processer with your choice of "food glue" (mayonnaise or salad dressing) and seasonings (dill pickle, mustard, spices, ...)
