Tuna Salad with Pickled Red Onions and Capers
Tuna Salad with Pickled Red Onions and Capers © kvalifood.com
This tuna salad is different from the classic tuna salad with sweetcorn and mayo. Here it is capers and pickled red onions that give the character, and the dressing is lighter. Use tinned tuna in olive oil — it tastes better than tuna in water. Lemon zest adds freshness.
