Here is one of my favorite summertime recipes that I make using fresh tomatoes and basil from my garden. Of course it will work with store or farmer's market bought tomatoes and basil too. I normally don't measure things when I cook, so all the measurements listed are approximate and can be adjusted to your tastes.
Pasta with Fresh Tomato, Basil, and Garlic
Enough pasta for one large main course serving
2 medium sized tomatoes, coarsely chopped
1/8 cup chopped fresh sweet basil
1 clove garlic, minced
1 tbsp olive oil
salt and pepper to taste
grated Parmesan cheese, optional
Mix together the tomatoes, basil, garlic, olive oil, salt, and pepper. Cook the pasta. Combine the sauce with the hot pasta. Spinkle with Parmesan cheese if desired.
