They are better micro'd. Better than warmed in the oven. Just enough to get some warmth in them. I think sliced bread has been replaced as "the best thing since...". I still haven't had a burger on one. Tried to last week. Closed the lid and walked away for a few. Was standing at the kitchen sink and I see the neighbour heading over to to the front door. She went to answer it and I headed back out to deal with the burgers. Smoke and fire everywhere. Well, in the grill. That wwas what he was coming over to tell us. It was pretty impressive.
