They make some foil looking stuff that browns things in the nuker. I had some and it worked.

Left over steak will heat up fine if you just get it to the “hot” point.

Cheep hot dogs and pre cooked sausages come out ok for a fast snack. Jalapeno and cheese sausages, wrapped in a flour tortilla and topped w/ mayo, are frequent requests at my house… and done in tha nuker.
