I have hardly any countertop space left and may purchase an origami folding kitchen cart with butcher block top. I know that I can store many heavy items on the top and the shelves below on this cart, but would like to use a toaster oven (do not have one yet) on it. If I place it on the kitchen counters, the above cupboards will be very close to the toaster oven.
Can anyone suggest what I could place under the toaster oven and on top of butcher block so there will not be a fire? I have a stainless steel baking sheet. Would love to hear if you have any other ideas.
