This is an original recipe: I do not use a cook book, nor did I copied the recipe, but since I find the dish very palatable, I decided to share my recipe with the world.
Warm up the oil in the cooking pan, while finely cutting the onion.
Add some spices #4, 5, 6, 7 and the chopped bell pepper. Stir often, so the onions brown evenly.
When the onions are ready add the mushrooms, broken or cut, in not too little pieces, stems and all, and stir so the mushrooms are on the bottom of the pot. When you start smelling the mushrooms, add the liver, in direct contact with the pan (you may need to move the vegetables aside. Add again spices # 4, 5, 6, 7, on top of the liver.
Skin the hot peppers with a potato peeler, and spread them.
After few minutes, turn the liver on the other side and add again the spices.
After one minute poor the red wine, so the liver gets to soften up. After another minute turn it over again, and cover it with the vegetables. After another minute, turn the liver over once again and add, on top A1 steak sauce, or your choice of steak sauce, remove from stove , and let rest for 5 minutes. Your natural source of iron is now ready to consume. Have a serving of beef liver once a week.
You can have salad, or half a baked potato. Avoid junk food, it would be a pity, and unhealthy too.
