Why This Recipe Works
- Tuna is one of the best sources of heart-healthy omega-3 fatty acids. These fats help reduce inflammation and support healthy triglyceride levels. Canned light tuna is low in mercury and affordable — a practical protein for every week, not just special occasions.
- White beans add fiber and plant protein that keeps you full. One half-cup of white beans provides about 8 grams of fiber, which slows digestion and helps blood sugar stay steady after eating. They also add a creamy texture that binds the filling together without mayonnaise.
- Lettuce wraps keep sodium and calories low without sacrificing satisfaction. Replacing bread or tortillas with romaine or butter lettuce cuts down on sodium — important for anyone managing blood pressure. The crunch of the lettuce also makes the whole wrap more enjoyable to eat.
Ingredients:
- 2 cans (5 oz each) light tuna packed in water, drained
- 1 can (15 oz) white beans (cannellini or navy), rinsed and drained
- 2 stalks celery, finely diced
- ¼ red onion, finely diced
- 2 tablespoons lemon juice (about 1 lemon)
- 2 tablespoons olive oil
- 1 tablespoon Dijon mustard
- ¼ cup fresh parsley, roughly chopped
- Salt and black pepper to taste
- 8 large romaine or butter lettuce leaves
- Optional: ½ avocado, sliced, for topping
- Optional: cherry tomatoes, halved, for serving alongside

Notes & Substitutions:
- Renal note: If limiting phosphorus, reduce the bean portion to ¼ cup per serving. Skip any cheese topping. Avocado is higher in potassium — omit if your care team has advised a potassium restriction.
- Make it lower sodium: Choose low-sodium or no-salt-added canned tuna and white beans, and reduce or skip the added salt.
- Add more crunch: Add diced cucumber or radish to the filling for extra texture.
- Protein swap: Replace tuna with canned salmon or mashed chickpeas for a different flavor and similar nutrition.
- Storage: The tuna-bean filling keeps in the refrigerator for up to 3 days. Assemble wraps fresh — lettuce becomes soggy if filled ahead.
