Mum made this for me, literally off the top of her head.
I bought some Sanitarium 'Vegie Delights Not Burgers' and a pack of Tofutti 'Cheese' lying around that I had no idea what to do with.
Luckily for me, my mother is a clever woman, and before I knew it, she whipped out a can of chopped tomatoes and tomato paste.
She spread the paste on the Not Burger, followed by the chopped tomatoes, and then put a slice of the lovely Tofutti 'Cheese' on top.
She put it in the oven as instructed on the packet, and voila, it was done.
I also tried using it on the Vegie Delights 'Schnitzel' as well, it worked better on those I think.
It's cheap, easy to make, and verrrrrrrrry yummy.
From my mother, to you
