Step 1

Heat oven to 400 degrees F.  Slice polenta in about 1 inch thick slices, you want to get about 7 slices.  Heat a large skillet over medium heat and add olive oil and polenta slices.  Cook polenta until crispy, about 5 minutes on each side.

Step 2

In a medium sized oven safe pan (I like to use my cast iron skillet) mix together white beans, 1 1/2 cups tomato sauce and spinach.  Top with polenta slices and then then top each one of those with a spoonful of tomato sauce and about 1 tablespoon shredded cheese.

Step 3

Bake polenta until heated through and cheese is melted, about 20 minutes.  Garnish with fresh herbs before serving, if desired.
