Cook the elbow pasta according to box directions, in well-salted water. Drain and rinse with cold water. Cool to room temperature.
To a large mixing bowl add all the salad ingredients.
In a small mixing bowl, whisk together all the dressing ingredients. Pour over salad and toss together until everything is well coated.
Chill for 6 hours or overnight. If the dressing is too thick, add milk, a tablespoon at a time, until you reach desired consistency.
Spread out salad onto a serving platter. Top with garnish and serve!
Notes
Food Safety - Keep in mind that mayo-based pasta salads have special handling instructions for food safety when serving unrefrigerated for any length of time, such as get-togethers and potlucks. Here’s more about that from the FDA and Food Network.
Pasta Prep - First, make sure you put plenty of salt in your pasta water. This will give your pasta some flavor. It absorbs the water as it cooks and if the water is salty, it will help infuse flavor into your pasta before it ever hits the salad. Otherwise, you could be in for a snoozer of a dish.
Must Be Al Dente - Cooking your pasta al dente is also important. Typically, it takes around 7-9 minutes, but the time may increase with the amount of pasta you’re making. Al dente pasta is still a little firm in the middle. A mushy texture will ruin the dish.
Same Size - Chopping all the veggies roughly the same size is another way to polish up your simple tuna macaroni salad. It allows people to get a refreshing variety of flavors and textures in every bite.
Doubling The Recipe - Don’t forget that this pasta salad calls for 16 ounces of pasta and 4 cans of tuna fish. If you are cutting or doubling the recipe (especially the pasta), you’ll need to adjust the tuna and the dressing as well.
