Directions
Cook the sweet potatoes: put the potatoes in a medium sauce pan, add the salt and cover with cold water. Bring to a boil; reduce heat to medium and cook for 8-10 minutes, until the potatoes are fork-tender. Drain in a colander and set aside.

Heat olive oil in a skillet to medium-high. Add mushrooms, walnuts, onions and soy sauce and sauté for 8-10 minutes, until the mushrooms and onions are softened and slightly browned. Add the garlic and vinegar and cook for 1 more minute. Remove from heat and stir in quinoa. Adjust seasoning with salt, pepper and more soy/tamari sauce, if needed.

Mash cooked sweet potatoes in a bowl and add quinoa mixture. Stir to combine. Let the mixture cool for a few minutes if it's too hot to handle at this point. Using your hands, scoop out 3/4 cup of the mixture and form a patty. Repeat until the mixture is gone.

Cook the patties in a lightly oiled skillet over medium for 5-7 minutes on each side. to assemble the burgers, place a patty on the bottom side of a bun. Add a patty and your toppings. Serve right away.
