What do all of you use to heat foods in convection ovens?

[Guest guest]

Off Topic but I really need to know. I have this beautiful Farberware Convection

oven (that also dehydrates). It's been sitting in my closet for over 20 years.

Paid $99.00 for it when I bought it. I maybe used it no more than 10 times in my

life.

It works fine. I just heated up something for Alan in it.

I know we don't like to use anything aluminum, right? So other than Pyrex stuff,

what is there to use to heat up food or cook in?

And because I still have aluminum trays, can put parchment paper on the bottom

of the aluminum tray and THEN put the food in this to heat in the convection

oven?

I want to start using this oven instead of heating up my kitchen when the

weather gets hot.

Thanks
