Heat a large sauté pan to medium-high heat, add a little bit of oil (optional), and sauté mushrooms until golden brown, about 6-7 minutes. Remove mushrooms from pan and set aside.
Using a food processor, mix the mushrooms, rice, black beans, figs, mint, bread crumbs, and salt. Pulse a couple of times until everything incorporated together, but is not completely mashed. Try to preserve some of the texture of the beans and rice.
Shape the mix into equal sized balls. In the same sauté pan, set to medium heat, brown the meatballs in a little bit of oil until golden brown all over. (You can also bake them at 375°F for 20 to 30 min, flipping them half-way through.)
