Stir together beaten eggs, ricotta, spinach, cilantro and salt plus 1 cup Monterey Jack.
Mash beans with a potato masher, I actually throw them in the food processor for a few seconds which saves a lot of work
Stir in pasta sauce and cumin
Spread 1/3 of bean mixture on bottom of a lightly greased 13x9" baking dish
Layer with 3 noodles, half of spinach mixture and 1 cup Monterey Jack
Spread with 1/3 bean mixture and top with remaining noodles and bean mixture.
Bake covered at 350 degrees for one hour, then uncover and top with remaining cheese. Bake 5 minutes more or till cheese melts.
