I was running later than usual and told David I wanted to eat a simple pasta for dinner. I was thinking we might do a simple fresh tomato pasta of the kind that is best eaten during late summer when the tomatoes are perfect for barely cooking. Little did I know that he was going in an entirely different direction! Being extremely talented and knowledgable about seasonal cooking he came up with this pasta. Summer squash is really mild but has a great flavor if you just cook it with a few other ingredients to make it stand out. Caramelized onions are the base you build the rest of pasta on top of.
