It's a spicy dish that uses ingredients typical of Mexican cuisine. I called it assorted because you can use leftover ingredients from the fridge instead of throwing them out.
It'll save you money and allow you to be creative, plus feed 3-4 people while at it.
Braise the sausage in a deep pan, to it add the chopped into crescents onions, pepper and garlic and leave them to braise. Next, add the spices and tomato paste.
Let everything simmer on low heat, covered with a lid, for 5 more min. Sprinkle with parsley and serve right away.
