Wash the liver thoroughly, cut it into medium-sized strips, and cook it in a pan with oil. Separately, sauté the chili strips, and when the liver is almost cooked, add them. Now, sauté the onions in the same pan used for the chilies, and when they change color, add them to the liver. Mix everything together, adding 2 cups of chicken or pork broth, and let it cook for another 25 minutes. And it's ready, mmmm.
