From Archie Perugi

1 Cotechino sausage (can be found in NYC or even your local Italian market!)
2-1/2 C. large lentils, washed and dry

2 small onions or 1 large, diced
1/4 c chopped pancetta
1 tsp. chopped garlic
2 stalks celery, diced
2 medium carrots, diced
1 can tomato sauce or 1 cup homemade sauce

Boil sausage in water for 1 – 1 1/2 hours.
Remove from water and add lentils to water and boil.
Saute chopped onions in olive oil, then add pancetta,carrots, celery, and garlic.

Add  partially cooked lentils to the carrots, etc. Then add the tomato sauce and sausage. Add some of the sausage water. Pierce the sausage to release the juices into the lentil mixture. Cook for 45 minutes over medium heat or until the lentils are soft.

Serve with sliced sausage on top.
