👨🍳 Chefy Tip: Use the oil from one tuna can in the dressing — it carries flavor. Add salt to the dressing, not the beans. Salt before acid stabilizes the seasoning. Flip the salad gently — you want flaked tuna distributed, not mush.
Combine cannellini beans, roasted peppers, and red onion in a large bowl.
Whisk together olive oil, sherry vinegar, garlic, salt, and pepper. Flake tuna over the bean mixture and pour dressing over.
Toss gently and fold in fresh parsley. Serve immediately or refrigerate up to 2 days.
Sherry vinegar is aged in oak barrels using the solera method — the same process as sherry wine — giving it a deeper, more complex flavor than standard wine vinegar. Oil-packed tuna retains significantly more omega-3 fatty acids than water-packed.
