Quinoa and Black Bean Veggie Burgers

Joe and I are on a veggie burger kick.  Because of the peculiarities of my diet, most of the store bought ones are off-limits to me, because they get their protein from either gluten or soy, so we've been making our own.  The actually taste a lot better than storebought, and you can't beat the price.
I've adapted the recipe from one I found on-line.  You can adjust the ingredients to suit your taste and what you have at home. 

1 can black beans

1-2 cups cooked quinoa

2 eggs

splash of water or milk

oats, ground flax or bread crumbs (maybe 1 cup)
1 cup grated cheese (optional)

salt and pepper

1 tablespoon cumin

1 tablespoon hot sauce

1 clove garlic, chopped (optional)

1 small can chopped green chiles (optional)

Drain beans and mush them up a bit with a fork or potato masher.

Beat eggs with a little bit of water or milk.

Mix eggs/beans/seasonings/quinoa/cheese together.  Add enough oats/flax (or breadcrumbs) to get the right consistency.   It should be kind of wet but hold together.  Put mixture in fridge for an hour or more to let it absorb the liquids.  Form into patties and cook like hamburgers.  (If you want them firmer, put them in a 350F oven for 10-15 minutes after pan-frying them.)
Makes about 10 large burgers or 15 medium ones.  They freeze well.
