Beyond the classic lettuce, tomato, and onion you will see in the ensalada mixtas in Northern Spain, the beauty of this recipe highlights the simple additions of pre-made and preserved ingredients. This is a beautiful recipe in that you can eat this salad as a full dinner, without feeling hungry at the end.
*With regards to boquerones, this is a vinegar-preserved anchovy, not salt-cured like we are used to seeing in the United States. The flavor is much more subtle. Boquerones are becoming more popular in the United States, and can be found at higher-end grocery stores like Whole Foods. They can convince people who hate anchovies to think twice about hating anchovies. They have a truly amazing flavor that is worth seeking out if you can find it.
