1: In a 4- to 6-quart Dutch oven, cook pasta according to package directions, adding corn for the last 3 minutes of cooking time. Using tongs, transfer corn to a large cutting board. Drain pasta. Rinse in cold water and drain again; set aside. Cool corn until easy to handle.
2: Meanwhile, coat an unheated large nonstick skillet with cooking spray. Preheat skillet over medium-high heat. Add beef strips. Cook for 4 to 6 minutes or until slightly pink in the center, stirring occasionally. (If using shredded beef, cook until heated through.) Remove from heat and cool slightly.
3: On a cutting board, place an ear of corn pointed end down. While holding corn firmly at stem end to keep in place, use a sharp knife to cut corn from cobs, leaving corn in planks; rotate cob as needed to cut corn from all sides. Repeat with the remaining ear of corn. In a large bowl, combine pasta, beef, tomatoes, basil, and the 2 tablespoons Parmesan cheese.
4: In a screw-top jar, combine vinegar, oil, garlic, salt, and pepper. Cover and shake well. Pour over pasta mixture; toss gently to coat. Gently fold in corn planks or place corn planks on top of individual servings. Serve immediately. If desired, garnish with additional Parmesan cheese.
