Good base but very bland, next time I would make it with chickpeas instead. I added lemon olives, garlic and parsley

Method
STEP 1
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.
STEP 2
Mix the oil, vinegar and tarragon together, then pour over the salad. Chill until ready to serve.
