Notes: I made these for supper tonight. It was pretty good. I may tweak the recipe a little next time. We both used Dijon mustard as a condiment and both thought it was a little overpowering.
Edit: We had the leftover burgers the following night, this time using vegan mayonnaise and whole wheat skinny buns. We liked them this way better.

Ingredients:
1 can black beans, rinsed and drained
1 can tomatoes with zesty mild chilies, drained
1 garlic clove, minced or pressed, or 1 teaspoon garlic powder
1 teaspoon onion powder
2 green onions, chopped
1 cup chopped carrots
1 cup parsley or cilantro
2 cups quick rolled oats
8 whole grain buns
Fresh veggie toppings and healthy condiments

Directions:
Preheat oven to 450º. Process the first seven ingredients using an immersion or a regular blender or food processor. Remove contents into a large bowl and stir in the oats. Form into patties, place on a sprayed baking sheet and bake for 8 minutes (if you did not use Quick Oats, bake for 16 minutes). Turn oven up to broil and cook for 2-3 more minutes, until the tops are nicely browned. Toast the buns and pile on your favorite toppings.
Variation:
Sauté the burgers on medium heat in a sprayed nonstick skillet for 5 minutes on each side, until both sides are browned.
