I found this recipe in a magazine by Martha Stewart and really liked it. My husband said it was a keeper so I thought you might enjoy it to. I did add one ingredient and that was 1 teas. of Ancho chili pepper for some added spice.
In a large pot of boiling salted water, cook pasta according to package instructions. Drain and return to pot. Meanwhile, in a large skillet heat oil over medium heat. Add garlic and onion and cook until onion is translucent, 3 minutes.
Increase heat to medium-high, add beef, and cook, breaking up meat with a wooden spoon, until no longer pink, about 5 minutes. Add cumin and cook until fragrant, 1 minute. Season with salt and pepper.
Add corn and zucchini and cook until zucchini is crisp-tender, 2 minutes. Add Tomatoes and juice, bring to a simmer, and cook until mixture is heated through, about 3 minutes.
Mix in pasta and stir until well blended. Serve in bowls and top with cheese.
I added the 1 teaspoon of ancho chili pepper when I added the cumin. We like the flavor of the ancho and it doesn't add a lot of heat--just a nice spicy flavor.
