In a 3 quart casserole dish or larger, pile the pimento cheese in the center. Sprinkle the halved cherry or grape tomatoes around the pimento cheese followed by the rest of ingredients, except for the cooked pasta.
Bake at 350 degrees, uncovered, for 30-40 minutes or until the top of the pimento cheese is golden brown.
Stir the pimento cheese into the vegetables to make the sauce. Next, mix in the cooked pasta. I start off with 2 cups of pasta and add more if I think it needs it. I like my pasta pretty saucy, so I usually stick with about 2 cups worth.
