This easy skillet dinner is a modified version of one of my very favorite recipes, Skillet Sausage Pasta with Spinach. This time I used zucchini and yellow squash and omitted the tomatoes. When preparing this one, you will want to add more water, but don’t! The squash will add more liquid as it cooks, and you don’t want to end up with a watery sauce. Just stir frequently, and the pasta will cook thoroughly. Promise!
