Cook the quinoa. When finished, place in a large mixing bowl.
In a small fry pan, saute the diced onion until softened. In a food processor, blend the remaining ingredients with the 1/4 cup of water, adding the sauteed onions. Combine mixture with quinoa in bowl. Mix well.
Form into 18 burgers and place on an oiled baking sheet. Bake in a pre-heated oven at 180C/350F until crispy on the top side (25-30 minutes). Flip and continue to bake until the outside of the burgers are crispy (about 15 more minutes).
