Open chorizos lengthwise without separating the halves. In a pan, over medium temperature, heat 2 tablespoons of olive oil and saute the chorizos for about 3 to 4 minutes on each side.
Cut the Cuban bread (or french bread) in halves, warm in broiler oven for a few minutes.
Place chorizos and pour some of the juice on the bread. Add chopped onions,
shoestring potatos, close sandwich and enjoy.
