This sweet potato patties recipe is one of my favorites. I use brown rice a lot in my healthy vegan recipes. It is a rich source of lots of nutrients, and makes for a much lighter patty than a bean-based veggie burger. This recipe is simple and delicious. It allows for a lot of variation in seasoning, and can easily be made with potato rather than sweet potato for a more neutral flavor. I've kept things really simple here to focus attention on the sweet potato.
