It cooks basically the same stuff you would cook by frying. It saves on a lot of oil (but you still need some) but the basket can be annoying to clean.

Oh shit, I honestly would have to ask my partner for a full list of whatever we put in there, but things that you'd fry (obviously) work excellently, nothing comes to mind that turned out bad. We are on a vegan diet for many years now, so vegan replacements, veggies and all sorta shit tastes awesome. I had my gallbladder removed therefore I can't really eat much of oily things and this has been a good and reliable solution to this problem. Vegan meatballs, schnitzels, umm sausages, anything, yummy. Actually mom got it from dad some time ago as a gift to make cooking easy for her, but we use it too and it's a nice addition to a kitchen if you can put money aside for it and the up in electricity doesn't bother you. Hard to call it a substitute as you may definitely have cases where it may be not the first choice of a chef's, but it's nice to have around.
