While a pasta salad is most often considered a picnic or cookout dish, this tuna macaroni salad can be served with lunch or dinner any time of the year. Enjoy this flavorful dish with sandwiches or along with an everyday family meal. A basic macaroni salad like this one is a great starting point. Add vegetables to give it extra color and crunch. Yellow bell peppers, shredded carrots, sliced ripe or green olives, diced cucumber, and diced plum tomatoes are just a few of the possibilities. Tuna is the protein in the dish, but diced cooked chicken, turkey, or ham are good choices as well. Or make it with small cooked shrimp, diced lobster, or crab meat.
