In a large bowl, mix all the ingredients except the noodles and 2/3 of the shredded mozzarella to make the sauce.
Lightly spray a 9x13 baking dish with cooking spray. Pour a thin layer of sauce on the bottom of the baking dish. Add 1/2 of the uncooked noodles, 1/2 of the remaining sauce and repeat using up the noodles and sauce. Top with the remaining mozzarella. Cover with seran and refrigerate over night. (If you cover with tin foil the acid in the sauce will eat holes in it.)
To prepare: Before baking, pour 1 1/2 cups cold water around the edges of the dish, but NOT IN THE CENTER. Bake, lightly covered,(use tinfoil sprayed with cooking spray) at 350* for 1 hour and 15 min. Let set for 15 min.
Chopped spinach or sliced zucchini can be substituted for the chopped broccoli. A combination of vegetables can also be used for variety.
