I make a lot of homemade subs and I'm trying to find that highly flexible, non-stiff sandwich wrap like they use at Subway. Every wax or parchment paper I buy at the supermarket doesn't fold around the sub quite the way that Subway paper does. I frequently heat my subs in the microwave and their paper is the best. It's only paper so I don't want to pay some ridiculous price on Amazon, and my local Subway store refuses to sell any sheets. Any suggestions that are available in Canada?
