Slice the casing with a knife and remove and discard the casings.
2. Cooking meat
Heat a skillet over medium heat. Add the sausage. Cook stirring, breaking down the clumps, until the chorizo is browned and cooked through (about 7 minutes. Discard excess grease if you find it necessary (it wlil depend on the sausage you use).Stir in onion and cook and stir until it turns translucent. Add pepper and olives and cook stirring for a minute.Pour in tomato sauce and stir until it is heated through. Season with salt to taste (I didn't add any). Remove from the heat and sprinkle with parsley (optional).
3. Using extra ingredients
For empanadas and pastelitos, you can mix in the minced boiled egg or the diced boiled potato. Alternatively, you can stuff empanadas with cheese and this chorizo stuffing.
