Tips
Soak the red onion in vinegar for at least 10 minutes to mellow its bite and create a tangy component.
Drain the tuna well if you prefer a less oily salad, but the oil adds richness and binds the ingredients.
Good to Know
Cover and refrigerate up to 2 days; dress just before serving to prevent greens from wilting.
Soak the red onion in vinegar up to 8 hours ahead. Prepare beans and eggs separately; assemble salad base just before serving.
Serve chilled or at room temperature on individual plates. Add dressing ingredients to taste just before serving.
Common Mistakes
Do not over-dress with lemon juice or olive oil at once; add gradually to taste to avoid oversalting or masking other flavors.
Do not assemble the full salad more than 30 minutes ahead; lettuce will become soggy.
