I made the burgers with a little potato and lentil paste. It is a good idea to add soy nuggets. I I added shredded onion, chopped green chilies, salt, a little pepper to it and mixed everything very well. I made it the way I make my fritters. That means, I made round flat shapes out of it and shallow fried them well, flipping sides.
I bought the breads from a local bakery. Since, I haven't yet learnt making vegan cheese, our slider wasn't "cheesy" but that did not lessen the fun!
