To make filling, in nonstick skillet, heat olive oil. Add SPAM® Classic; cook until SPAM® is lightly browned. Add cabbage and onions; cook 2 minutes. Stir in soy sauce, sugar and sesame oil. Add cornstarch mixture; mix well. Cook 2 to 3 minutes longer or until thickened. Remove from skillet to cool.
Heat oven to 375°F.
Divide dough evenly into 8 pieces; shape each into flat round disc. Fill each piece dough with about 1 tablespoon filling. Close and pinch ends of dough together to make round balls. Place balls seam-side-down on baking sheet. Bake 10 minutes or until lightly browned. Serve and enjoy!
