Lol, that is not at all the intended use case. But good on them for simplifying the process, I guess. The point, of course, is to cook them on separate sheets, but at the same temperature for the same time. So one use of the oven for both supper and dessert.

But, now I kind of want to try it.

Take this from someone who learned it the hard way: chocolate and tomato do NOT taste good together.

Jalapeño + pepperoni + pineapple. The first two balance out the pineapple perfectly, moreso than ham IMHO.
