Distribute the clean lettuce leaves on a pretty (or practical) plate, place one or two anchovies on top of each one, drizzle with a bit of the oil left in the tin and then drizzle with the juices left in the frying pan after cooking the chorizo.
Tip: you can also mix the oil from the tin of anchovies with a scant ¼ teaspoon of paprika and ignore the chorizo part
