The picture just isn't that descriptive. My bet is that it is a non-stick coated roasting pan, with silicone sides. Th sides would make it easier to handle that metal sides. This pan would be great for roasting veggies, or something small, like a cornish game hen, or maybe two chicken breasts, or sausages, etc. It would be great for frozen french fries, or sweet potato fries. This of course, assumes that the cookware is oven safe.
You could make some funky looking flat bread with that pan.
Be creative with it. Experiment a little. Roast some hot dogs on it, or better yet, some pigs in the blanket.
