First, the burgers: I made a wet mixture of 2 cans of squashed kidney and pinto beans, minced red onion, cooked corn kernels, 1 egg, and some oats. I spiced it up with cayenne, chili powder, cumin, and salt, and made patties that I sauteed in a pan with some veggie oil till they were browned on both sides.
Next came the blinis: 1/2 c. chickpea flour (gram), 1/2 c. cornmeal, 1/4 tsp. baking powder, 1 tbsp. salt, 2 eggs, 1/2 c. yogurt, 1/2 c. milk - makes a thin batter that you can make silver dollar cakes with in a dry non-stick skillet over medium heat.
Sandwich a bean patty between two of these blinis with a bitter green and some avocado and BLAM, welcome to Yum City.
