In a large bowl, combine the first nine ingredients. Crumble beef over mixture and mix well. Divide into 16 portions; flatten. Top each with a cheese cube; form beef mixture around cheese into meatballs.
Place on a greased rack in a shallow baking pan. Bake, uncovered, at 400° for 20-25 minutes or until no longer pink. In a small saucepan, heat the marmalade, orange juice, half of the green onions and the jalapeno.
Place meatballs in a serving dish; pour glaze over the top and gently stir to coat. Garnish with remaining green onions. Yield: 16 meatballs.
