Drain the canned chickpeas and add them to a blender with the eggs. Blend on a medium setting to combine, leaving some texture.
Finely chop the onions, mushrooms, peppers and garlic. Add the first three vegetables to a skillet and the olive oil and cook the veggies over medium-high heat until soft, about 4 to 5 minutes. Add the garlic at the last minute.
Add the spices to the vegetables and continue cooking for about one minute. Add the soy sauce and stir until well combined.
Let the vegetables cool, and then combine with the chickpea/egg mixture.
Add the oats and bread crumbs to the mixture and mix well. Let stand for about 15 minutes until the liquid is absorbed.
Form the mixture into about 8 patties. If the veggie mixture does not stick together, add more bread crumbs and oats until it is dry enough to form patties.
Grill the veggie patties on a hot grill or in a skillet for about 4 minutes on each side. Add your favourite toppings and serve on a bun. I recommend the sprouted burger buns by Alvarado Street Bakery.
