MAPLE SWEET & SOUR DRIZZLE: In a small saucepan, bring the maple syrup and vinegar to a boil. Slow boil for 1-2 minutes or until the sauce reduces a little. Then simmer for about 5 minutes.
While the maple sweet and sour drizzle simmers, in a large mixing bowl combine all of the MEATBALL ingredients. Shape into 18-24 golf ball-sized and place them on a plate or pan.
In a shallow pan, heat the oil on medium-high until it sizzles.
Lower the heat and cook the meatballs in two batches, about 7-9 minutes each, turning them once in a while to brown evenly on all sides. Set aside on a plate and repeat until all of the meatballs are browned.
Serve the meatballs with the MAPLE SWEET & SOUR DRIZZLE and a sprinkle of sea salt.
