Polenta spaghetti casserole

This was one of my own creations. I bought polenta intending to make Polenta Tamale Pie:

But I bought basil and garlic flavored polenta instead of plain, so I made up a different recipe instead:

You will need:
1 2-lb roll of polenta
1 lb spaghetti
1 jar spaghetti sauce (meat sauce would give it extra protein, or non-meat would make this a vegetarian option)
2 cups shredded cheddar

Directions
Break pasta into 2 inch pieces, then cook until al dente, mix with pasta sauce in large bowl. Grease glass baking pan and pour pasta into it. Slice polenta into squares and layer on top, then sprinkle cheese. Bake covered at 350 for about 45 min.
