For my nicoise-style tuna salad, just open three cans: one each of tuna, white beans and sliced olives. Toss these ingredients with slivered red onion, olive oil and lemon juice. Take time, if you like, to boil eggs, or pick them up at the grocery salad bar. Serve the salad with steamed green beans. For an even simpler version, add a little chopped parsley to the salad for color and serve it with salted tomato slices.
