White beans with tomatoes over polenta -- so easy, so delicious

This vegan dish starts with an aromatic-veggie base—aromatics include onions, celery, carrots and similar fragrant and flavorful vegetables. You add peppers, mushrooms, tomatoes and spinach along with cannellini beans. Spoon this sauce over polenta disks sauteed in a little olive oil, but it would be just as tasty tossed with multigrain pasta (such as penne or farfalle) or piled on a mound of rice.

Faithful readers will recognize this recipe from late summer, but I think it’s wonderful on a rainy night in late fall. So I’m posting it again.
