I have a Cuisinart toaster oven that came with an 11 1/2" X 10" rimmed baking pan. It's stainless steel. I would prefer an aluminum pan for better conductivity. Something like professional sheet pans. I can't find any online close to these dimensions, most are too small. Also, something to heat up to produce "bottom heat" for pizzas or pie crusts. Maybe a 1/4" thick piece of raw steel or pizza stone. Thanks!
