"I was amazed at how delicious this turned out. Sausages cooked in a simple tomato sauce and served atop hot rice (risotto, or even pasta) is a great winter-time meal." - ketherian
Sear off the sausages in a hot pan. Drain any excess oil. Add the garlic, onion, and sage. Stir to incorporate. Add a can of pureed tomatoes and deglaze the pan. When this has cooked for a good twenty minutes, add the beans, and other seasonings. Allow to boil down for another 20 minutes. Serve hot over bread, rice, or polenta.
