Because of food allergies (and an aversion to eating meat), I have to use my imagination quite a lot in order to get enough protein in my diet. I would LOVE to be able to eat a fried egg and cheese sandwich, or a fried tofu sandwich, or a grilled cheese sandwich with tomato bisque soup on the side, or any number of other sandwiches that involve eggs, cheese, and/or soy products. But that's not possible for me at this time.

In my potato-lentil burgers, the potato and tapioca flour are used as binding agents for the lentils (in place of eggs). Luckily for me, the potatoes taste really good in these burgers. I get tapioca flour in bulk from one of the local natural food stores.
