Here's a tasty way to transform ordinary canned tuna into a delicious lunch. These low-calorie, low-carb lettuce wraps are filled with hearts of palm, tomatoes, carrots and onion and topped with a light avocado dressing. I found two to fill me up, but the calories are low enough you could easily eat three. Using a good quality tuna in oil makes all the difference in flavor here.
I made the avocado yogurt dressing in my magic bullet, it makes a larger portion than is needed in this recipe but it can easily be stored in an air-tight container in the refrigerator and used a veggie or cracker dip, salad topper or drizzled over grilled fish.
If you're not familiar with hearts of palm, they come canned or in a glass container available at Trader Joes or in most supermarkets. They make a great addition to salads.
