Curtido is a spicy cabbage slaw often served with pupusas.
Chopped cabbage
1 medium onion, sliced
Carrot, finely shredded
Cooked green beans, not too soft (optional)
Beets (optional)
Grated horseradish (optional)
Red pepper, finely chopped (optional)
1 teaspoon oregano
Vinegar or lime juice to taste
Water, to taste
Salt to taste
Quickly swirl the cabbage in a pot of boiling water, then drain.
Combine all the ingredients in a glass or plastic container, and mix with a wooden spoon (never metal).
Put the container in the refrigerator, and let it rest for a week so that the ingredients pickle.
