Tuna and Curly Endive Salad with Romesco Vinaigrette (Xató)

Curly endive, with its pale green and white leaves and pleasantly bitter taste, is the basis for this wonderful winter salad of Barcelona. Here, the endive is topped with tuna and then dressed with a piquant vinaigrette adapted from the region's classic almond-based romesco sauce. The salad is also sometimes made with salt cod or a mixture of tuna and salt cod.

Ingredients

For the vinaigrette:

Directions

To make the vinaigrette, in a food processor, combine the almonds, garlic and red pepper flakes. Pulse until the mixture is the consistency of fine crumbs. Add the bell pepper and pulse to combine. Pour in the vinegar and process until pureed. Gradually add the olive oil in a slow, steady stream, processing until the oil is emulsified and the vinaigrette is the consistency of thick cream. If it is too thick, thin with a little water. Season with salt and black pepper.

Distribute the endive leaves evenly among individual plates. Break up the tuna into bite-size pieces and arrange it on top of the endive. Drizzle the vinaigrette over the top and garnish with the hard-cooked eggs and olives. Serve immediately.
