Can one cook two things in a disposable aluminum pan or would that be considered “re-using” and therefore require tevila? For example, could one cook spinach in the pan and then leave it in there and add eggs to combine the eggs and spinach? Or should they be cooked in separate pans? Or could one make pasta in a pan and then add the sauce to heat it together?
I am new to the idea of tevila and do not know what counts as re-using or not. thank you
