These are a low-calorie, low-carb, but very tasty, light alternative to a tuna wrap sandwich! Try to choose larger leaves of lettuce with no tears or holes; lettuce leaves are replacing the tortilla in a traditional wrap sandwich. Cheese is optional, but even a little adds a lot of flavor.
For best results, ensure the tuna is very well-drained; excess moisture can make the wraps soggy. Finely dicing the onion allows for better flavor distribution without overpowering the delicate tuna. Consider chilling your lettuce leaves before assembly for an extra crisp texture. For enhanced flavor, a squeeze of fresh lemon juice or a pinch of fresh dill can elevate the tuna mixture. To add a textural contrast, finely diced celery or water chestnuts can be incorporated. When rolling, be gentle to prevent tearing the lettuce, especially if using a softer variety.
