Summarize this article in one sentence.
Before heating your grill, use a paper towel dipped in a little cooking oil to grease the cooking surface. This will allow your steaks to be flipped much more easily as they are cooking. If you forget to oil your grill before beginning to preheat it, hold the oil-dipped paper towel with a long set of tongs to grease it. Preheating your grill before cooking the ham steaks will allow them to cook faster, and give you more delicious browning across the meat. Leave the grill to heat up while you prepare your ham steaks. If you don't have an outdoor grill, you can use a grill or griddle pan indoors to achieve a similar effect. If your ham steaks are still moist on the outside when put on the grill, the liquid will have to cook off before they begin browning. Use a couple of paper towels to remove any excess liquid on the outside of your ham steaks before cooking them. Evenly space your ham steaks across the surface of the grill and leave them to cook on one side for around 4 to 5 minutes. They may start browning at this point, but shouldn't cook completely. Use a pair of tongs or a grilling fork to flip your ham steaks over. Let them cook on the other side for another 4 to 5 minutes. During this time, lightly brush any glaze you want to apply to the ham steak across the side you can see. Flip your ham steak over and glaze the other side. Continue flipping your ham steaks and glazing them until they have grill marks on each side and are heated through. Transfer your ham steaks off the grill and onto a serving plate to eat immediately. If they're not all eaten, they can be stored for 2 to 3 days in the fridge before they'll need throwing out. For a little extra flavor, brush over some of your remaining glaze just before serving your ham steaks.

Summary:
Brush down your grill with oil. Turn your grill onto a medium to high heat. Pat your ham steaks dry with a few paper towels. Grill your ham steaks for 4 to 5 minutes on one side. Flip your ham steaks to cook for another 4 to 5 minutes and apply any glaze. Keep flipping and glazing until the ham steaks are browned and cooked through. Take the ham steaks off the grill and serve them immediately.
