"Heartbeet" Vegetable Burgers
For easy measuring, 2 sweet potatoes will yield roughly 2 1/2 cups when boiled and mashed.
My trail mix had pumpkin seeds, sunflower seeds, cranberries, peanuts, and cashews.
The onion taste comes through quite strongly, so feel free to cook your onion first or substitute a shallot instead.
I like to make my burgers heart-shaped.
