About ten years ago, I bought one of those small countertop toaster ovens that is roughly big enough for four pieces of bread to lie flat in it. It became the best $100 I've ever spent. We cook everything small enough to fit in it, including toast with cheese :) . We've since only used our regular full-size oven maybe half as often, because this small countertop one is so much faster and more convenient

No need for an actual toaster, although this one takes a minute or two longer. As an added bonus, my mother-in-law hates waiting that extra minute or two, so that's a big win in my book.
