Looks like most operations that may be carried out in a regular oven can be accomplished in the so-called toaster oven, with all its time-temperature-function operations. Certainly they are handy, and a lot more can be done than the cheese-bacon high-cal suggestions that are showing up. A matter of testing to determine best time-temperature settings. Just looked at the instructions on ours for the first time and I see it is a '6-slice' with settings for warm, broil, bake and toast, temperature set and timer. Not bad for a $75 gadget.

My wife suggests having small lidded casserole and baking dishes rather than using foil as a cover; I would be careful with foil since it can cause overheating if it gets into the wrong place; The directions for mine say don't wrap the oven tray in foil.
