This is a great quick and easy meal. Keep a ham steak in the freezer and you can have it defrosted and cooked in 10-15 minutes. I really like the Smithfield brand. You don't have to do the mustard & brown sugar, but it is good.
Set oven to broil
Place ham steak in an oven-proof baking dish. Paint it with dijon-style mustard and sprinkle with brown sugar. Broil 5-10 minutes until browned. If there is a lot of juices in the pan, drain it off. (Ham is full of water) Slice into serving pieces and serve.
