Yellow Squash all'Amatriciana with Pancetta and Spicy Tomato Sauce

In a large saucepan, sauté the diced pancetta over moderate heat, stirring occasionally, until browned and the fat rendered, about 5 minutes. Add the onion, garlic and red pepper and sauté for 5 more minutes, until onions are soft and beginning to brown. Add the canned tomatoes with their juices, stir, and bring to a boil. Reduce heat to low and simmer, stirring occasionally for 40 minutes. Season with salt and pepper and keep warm.

In a large skillet, heat the oil over moderate heat. Add the squash and sauté for 2 minutes. Season with salt and pepper. Add 2 cups of the Amatriciana sauce, toss, and serve.
