Penne with Grilled Summer Squash, Sweeet Corn, and Shrimp

I think it's pretty obvious that we love pasta in our house. This recipe from a recent issue of Everyday with Rachael Ray used delicious summer vegetables and one of my favorites - ricotta cheese. I made it into a main meal by adding some shrimp to the mix. Chuck and I both agreed that this dish needed more flavor. The original recipe did not call for cooking the tomatoes, but my version below suggests sauteeing them a little with the garlic to add a little more depth.

Penne with Grilled Summer Squah, Sweet Corn, and Shrimp
adapted from Everyday with Rachael Ray
makes about 3 servings

1/2 pound penne pasta
1/2 pound large shrimp, peeled and deveined
2 yellow summer squash (just under a pound), halved crosswise and then cut into 3 thick slabs
3 tablespoons olive oil
salt and pepper
1 tomato, chopped
3/4 cup corn kernels (1 ear or use frozen)
1/2 of a 15-ounce contained ricotta cheese
1 clove garlic, grated
1 teaspoon chopped thyme

Preheat a grill to medium-high or a grill pan on the stove over medium-high heat.

Cook pasta in a large pot of salted, boiling water according to package directions. During last 3 minutes of cooking, add shrimp. Drain pasta and shrimp, reserving 1/2 cup of the cooking water.

Brush the squash pieces with 2 tablespoons olive oil and season with salt. Grill, turning once, until charred, about 10 minutes. Cool slightly, then coarsely chop and put in large bowl.

In small skillet, heat 1 tablespoon olive oil over medium heat. Add garlic, cook until fragrant, then add chopped tomatoes and cook until slightly softened, 3-4 minutes. Add to squash, along with ricotta cheese and thyme. Add the pasta and stir in some cooking water if needed.

Season to taste with salt and pepper. Serve immediately with Parmesan cheese, if desired.
