Start out by putting about 1/3 cup sauce in the bottom of a 9x13 pan
Layer with 1/3 package of cheese ravioli (20 oz. - the refrigerated type)
Add 5 oz. spinach (1/2 of 10 oz. box that has been thawed and squeezed good)
Add 4 oz. mozarella cheese (I was even lazier by not grating it)
Top with 1/3 of the leftover sauce
Repeat layers - ending with ravioli and sauce and then sprinkle 1/2 cup parmesan cheese
Bake at 375 covered for 30 minutes; remove foil and bake an additional 5 minutes; then sit about 5 minutes before serving
I'm sure you could experiment with different kinds of raviolis and sauces! Try it - you'll like it!
