Tuna salad is a great go-to lunch. It's healthy, filling, and easy to make. But it can be a little bland if you don't add something to give it some flavor (and a lot of people don't like mayo).That's why I think it's a good idea to put a dressing in your tuna salad. You can do this by mixing up some mustard and vinegar with the tuna before you mix it with the mayo. If you want more tanginess, add lemon juice or even pickle relish.This makes your tuna salad much more flavorful without adding too much calories or fat.
