Chargrilled octopus with saffron rouille and roasted onion and pimiento salad

Hanging around the fabulous La Boquería market (Mercat de Sant Josep) off the Ramblas in Barcelona inspired the flavours, textures and colour of this salad. Look for jars of roasted pimiento strips (also called piquillo peppers) in Spanish or gourmet food stores — they are a necessity if the success of this salad is to be ensured.
