Tomatoes can be roasted either of two ways - on the grill, or in the oven. If using the oven, line a baking sheet with foil, lay out tomatoes in a single layer, and bake for 10-20 minutes at 400 degrees, turning once half way through, til tomatoes are blistered.
If using the grill, preheat to medium heat. Lay a piece of foil on top of the grates and arrange tomatoes in a single layer on top of the foil. Grill for 10-20 minutes until tomatoes are blistered.
After tomatoes are cooked, transfer tomatoes to a blender or food processor. Add olive oil and McCormick's seasoning and pulse until pureed, but still a little chunky.
Transfer mixture to a sauce pan, cover and simmer for 10-15 minutes, stirring throughout. Taste and add salt and pepper to taste. Toss with your favorite pasta noodles and top with shredded parmesan cheese and fresh basil or parsley if desired. Store in airtight container
