How to Make It
Preheat oven to 400°.
Heat 1 1/2 teaspoons oil in a large nonstick skillet over medium-high heat. Add beef; cook 3 minutes or until browned, stirring to crumble. Drain. Wipe drippings from pan with a paper towel. Heat remaining 1 1/2 teaspoons oil in pan. Add zucchini and next 6 ingredients (through garlic); sauté 7 minutes or until vegetables are tender. Return beef to pan. Stir in wine, tomato paste, Worcestershire sauce, pepper, and broth. Bring to a boil; cook 3 minutes. Combine cornstarch and 2 tablespoons water in a small bowl; stir with a whisk. Add the cornstarch mixture to the pan; cook 1 minute, stirring constantly.
Spoon beef mixture into an 11 x 7-inch baking dish coated with cooking spray. Separate breadstick dough into strips. Arrange strips in a lattice fashion over beef mixture. Bake at 400° for 12 minutes or until browned.
