Fresh spinach, chicken, and a combination of cheeses make this pasta dish comforting enough for the last days of winter yet fresh enough for the first days of spring. Serve family style or portion out in individual ramekins. Either way, this penne pasta casserole is definitely worth sharing.
As you eat this unique recipe the juicy, roasted tomatoes break apart into the pasta to make the sauce right on your plate. People at the table might not even notice the extra serving of vegetables you "hid" by grating squash into the pasta, but the flavor will make it a winner.
