Cook 2 cups quinoa as directed on package. While cooking, dice green onions, garlic and onion.

Cool the quinoa and mix with parmesan cheese, eggs, bread crumbs and soy sauce, in a large mixing bowl; add diced veggies and season with salt and pepper to taste.

Drop 1/4 cup sized balls into a hot frying pan with a small amount of olive oil and smash them flat with a spatula. Cook one side until browned (about 4 minutes) then flip carefully with a spatula and let the other side cook until crisped up. Continue to cook, adding olive oil as needed, until all of the quinoa mixture has been used.

Serve a bun smeared with guacamole, topped with lettuce and a slice of tomato; watermelon on the side.
