I have only ever used a toaster oven for curing polymer clay!
But, with summer fast approaching, I might buy one to keep the house from heating up, so thanks for the idea.
I
love my wood pellet smoker and Weber kettle outside, but I could set up a toaster oven out there, too. We like roasted vegetables a lot more than steamed, boiled, baked or fried, so I've been using my oven a LOT during the winter.
