Mixed Meat Sauce

Rinse meat, pat dry and cut into pieces. Divide chicken into portions. 

Peel and rinse onion, celery and carrot, chop finely. Crush chile pepper in a mortar.

Drain tomatoes and chop coarsely.

Heat olive oil in a large saucepan and brown meat, few pieces at a time. Add onion, celery, carrot, chile pepper and parsley, saute briefly.

Deglaze pan with wine. Simmer until almost all liquid has evaporated and add broth (meat should be covered with liquid), season with salt. 

Reduce heat and simmer, covered, for about 1.5 hours on low heat. Add more broth as needed.
