1. Place first 3 ingredients in a mortar bowl or spice grinder; grind to a fine powder, using a pestle or spice grinder. Place chicken, next 6 ingredients, and crushed spices in a large bowl. Combine mixture with hands until blended and smooth (2 minutes). Cover and chill 1 hour.
2. Preheat oven to 400°. Drop mixture by rounded spoonfuls 1 1/2 inches apart onto a lightly greased aluminum foil-lined jelly-roll pan, using a medium-size cookie scoop (about 1 1/2 inches).
3. Bake at 400° for 10 to 12 minutes or until done. Toss meatballs with hot sauce. Serve on split rolls with Blue Cheese Sauce.
