In the bowl of a food processor, combine the chickpeas, onion, walnuts, breadcrumbs, parmesan, egg, 4 cloves of garlic, oregano, and a big pinch of salt and pepper. Pulse into a coarse but cohesive batter forms. Oil your hands and roll the batter into meatballs. You should get 14-16 depending on how big your balls are. Tehe.
Mince the remaining 2 cloves of garlic. In a bowl or jar, whisk or shake the balsamic vinegar, honey, the minced garlic, cayenne pepper, paprika, chili powder, cornstarch, and a pinch of salt and pepper.
Heat 2 tablespoons olive oil in a large skillet over medium heat. Add the meatballs and sear 8-10 minutes, turning every minute or two to brown each side. Remove.
Drizzle another teaspoon or two of olive oil in the pan if it looks to dry. Place the brussels sprouts cut side down into the oil. Sear 3-4 minutes, then sprinkle in a pinch of salt and pepper and toss for another 2-3 minutes.
Add the meatballs back to the pan. Pour in the sauce. Simmer until the sauce thickens and begins to coat the meatballs, about 2-3 minutes. I prefer to use a spoon to toss the sauce over the meatballs, since the balls are more fragile than the male ego (and regular meatballs), rather than flipping the balls around with a spoon or spatula.
Divide the meatballs and sprouts over rice. Drizzle with extra sauce and garnish with fresh herbs.
