Quarter the beets and pulse along with 2 cups of the black beans in a food processor until roughly chopped.
Step 2
Add beet-bean mixture to a large bowl, along with the next 13 ingredients (remaining black beans, brown rice, dried figs, oat flour, red onion, garlic, smoked paprika, brown mustard, ground cumin, ground coriander, thyme leaves, salt, pepper). Stir to combine, mashing the mixture together with a spatula or wooden spoon.
Step 3
Using a half cup measure, form six patties. Cover them with parchment paper or plastic wrap and transfer to the refrigerator to chill for 30 minutes.
Step 4
In a large skillet or on a griddle pan, heat an ⅛ inch of oil. Add the burgers and cook over medium heat, turning once, until browned and heated through, about 6 minutes. Serve with desired accompaniments.
