Cook the asparagus in a large pan of boiling water for 4-5 mins until tender. Drain well, cool under running water, then cut into finger-length pieces. Toss together the tuna, beans, onion, capers and asparagus in a large serving bowl.
Mix the oil, vinegar and tarragon together, then pour over the salad. Chill until ready to serve.
