Ravioli Lasagna.

Frozen raviolis (I did half meat & half cheese)
1 pkg frozen chopped spinach (10 oz. blocked works; set out 1 hr. early to thaw; press out any water), or fresh
tomato sauce (I just used the 28 oz. Hunt's can)
shredded mozzarella (no more than an 8 oz. bag)

*Use approximately a 8 x 11" glass Pyrex dish to bake in.

1. Spread 1/2 cup hot pasta sauce into a greased baking dish.
2. Layer with 3 cups frozen meat or cheese ravioli (no need to thaw).
3. 1 and 1/2 cups fresh spinach (or half of the thawed spinach).
4. 1/2 cup mozzarella cheese
5. 1 cup pasta sauce.
6. Repeat the layers (ravioli/spinach/cheese).  Top with any remaining sauce.
7. Cover with any remaining  mozzarella (aim for 1/2 cup).
8. Bake uncovered at 350 for 45 minutes, or until edges are bubbly and cheese is melted.  Let stand 5 minutes.
