Cook the brown rice by added 1/2 cup uncooked rice to 1 1/2 cups water with 1/2 tsp of salt. Cook until tender, about 20 mins. Set it aside to cool.
To the bowl of a food processor, add the chickpeas, garlic powder, oregano, lemon juice, Feta, egg, breadcrumbs, salt and pepper. Pulse until you get a coarse paste.
Add that to a bowl and then add the cooked rice to it. Mix well. Form 6 patties and place on a parchment line baking sheet. Refrigerate until to tighten up until ready to serve, at least 1 hour. These also freeze well! I like to store them between sheets of wax paper and place into a freezer bag.
Grease you grill or skillet with olive oil or avocado oil. Sear on both sides for about 4-5 mins on each side.
Toast your bun, place the burger on the bun add a generous amount of Tzatziki sauce and your choice of toppings. I like to add grilled red onion, fresh tomato and romaine lettuce.
