1. Preheat oven to 350ºF. To prepare filling, heat a large Dutch oven coated with cooking spray over medium heat. Add potato and onion; cover and cook 7 minutes, stirring occasionally. Add beef and next 6 ingredients (beef through garlic); cook, uncovered, 7 minutes or until browned, stirring to crumble. Lightly spoon flour into a dry measuring cup; level with a knife. Add flour to pan; cook for 1 minute. Gradually add beer, consomme, and tomatoes; bring mixture to a boil. Remove from heat, and stir in olives and vinegar.
2. Spoon mixture into an 11 x 7-inch baking dish coated with cooking spray. Unroll both dough portions (do not separate dough into breadsticks); roll dough together, forming a 12 x 10-inch rectangle. Place dough on top of beef mixture, pressing to edge of dish. Cut 5 slits in top of crust to allow steam to escape. Gently brush 1 tablespoon garlic spread that is packaged with breadsticks over crust; reserve remaining spread for another use.
3. Bake for 25 minutes or until golden brown and bubbly around the edges. Let stand 10 minutes before serving.
