Yes, so far have cooked hamburgers, hot dogs and pork chops on it. They came out great, love the grill. It's easy to clean and heats up fast. I use olive oil.
I did season the grill, my cast iron pan, and my stove griddle with Flax seed oil I got on Amazon. Much, much better than any other oil I used on the cast iron pan and griddle. It put down a really tough surface on the grill.
