Combine first 7 ingredients in a large bowl. Add beef; mix gently to combine. With moist hands, shape beef mixture into 20 (1½-inch) meatballs.
Heat a large cast-iron skillet over medium-high heat. Add half of the meatballs to pan; cook 4 minutes, turning to brown meatballs on all sides. Arrange browned meatballs in a single layer on a jelly-roll pan coated with cooking spray. Repeat procedure with remaining meatballs.
Bake meatballs at 400° for 7 minutes or until done.
Notes
Saute some bok choy in Trader's Joe's Soyaki sauce and chili paste until tender crisp (drizzle sauté sauce on meatballs and quinoa). Cook quinoa according to package directions - I recommend using chicken broth instead of water.
