Tuna Macaroni Salad with Green Olives

This Tuna Macaroni Salad with Green Olives is loaded with flavor due to good quality tuna in olive oil, chopped Spanish green olives, and a generous amount of lemon juice and green olive brine in the dressing. And I’m mentioning that because quite honestly, I think any kind of macaroni salad is always in danger of being a bit boring if you don’t use strongly flavored and interesting ingredients.

We also added finely chopped celery for a little crunch, and some sliced green onions for more flavor, and we devoured this for lunch on the day we tested the improved recipe and took these photos. And besides the great flavor, another things we loved about this macaroni salad with tuna is that it’s made with Fiber Gourmet Light Elbows, which was one thing that made the carb count much lower than usual for this type of salad!

And pasta salad weather is definitely here, so I’m recommending this favorite macaroni salad recipe as my Friday Favorites for the week, and I hope you try it over the weekend if you’re a fan of these ingredients!

How low in carbs is the Tuna Macaroni Salad?

This flavorful salad has only 10.1 net carbs and 14.5 grams of protein per serving when it’s made with Fiber Gourmet Light Elbows (affiliate link)!

How did we make a Tuna Macaroni Salad with fewer carbs?

• We used Fiber Gourmet Light Elbows (affiliate link) for the macaroni in the salad, and this high-fiber wheat pasta from Italy is a lot lower in net carbs than regular pasta.
• We used a lot of low-carb ingredients like tuna, green olives, and celery compared to the amount of macaroni.
• Using 8 oz. of the Fiber Gourmet Elbows (which would normally make 4 servings) to make 8 servings of salad not only reduced the amount of carbs, but it makes the Fiber Gourmet pasta less expensive per serving.

More about Fiber Gourmet Light Pasta:

The biggest drawback to the Fiber Gourmet Light Pasta for many people will be the price. I haven’t found it in stores near me, so I buy it at Amazon where you can buy a package of 6 boxes and get it for $6.66 per box (affiliate link). For me it’s such a treat to have “real” pasta without so many carbs that don’t mind buying six boxes at once. And since this recipe uses 4 servings of elbow macaroni to make 8 servings of salad, that also makes it more affordable.

What if you don’t like green olives?

There’s an archived recipe on the site for a tasty tuna and macaroni salad with made with Dill Pickles if you’re not a green olive fan.

How to make Tuna Macaroni Salad with Green Olives:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

1. This is the Fiber Gourmet Light Elbows (affiliate link) we used. Bring a pot of water to a boil, add some salt, and cook until the macaroni is al dente. (For us that took 15 minutes for the Fiber Gourmet Elbows; check package directions for other brands.)
2. Let tuna drain while you cook the pasta and prep other ingredients. (This colander is over a bowl because I don’t want the oil going down the sink.) 
3. When the pasta is cooked, dump into a colander and let it drain well.
4. Chop up 20 green olives and slice 4 olives to garnish the top of the salad. 
5. Chop the celery and thinly slice green onions
6. Stir together lemon juice (and zest if using) and green olive brine, and then whisk in mayo and Szeged Fish Rub (if using) to make the dressing. (Blogger fail; forgot to take a picture of that!)
7. Put the pasta, chopped green olives, chopped celery, and sliced green onions into bowl and mix together.
8. The mix in desired amount of dressing and stir until ingredients are well-coated with dressing. 
9. Gently stir in tuna, being careful not to over-mix; you want the tuna to remain in small chunks.
10. Season salad to taste with salt and fresh-ground black pepper, remembering that the olives are salty.
11. The Tuna Macaroni Salad salad can be chilled or served right away, and leftovers will be good in the fridge for a day or two.

Notes

We loved the Fiber Gourmet Light Elbows (affiliate link) for this recipe, but use any macaroni you prefer if you don't care about having fewer carbs.

We made this with two 5 oz. cans of Genova Tuna Packed in Olive Oil (affiliate link).

I used my fresh-frozen lemon juice for the dressing, but if you're squeezing a lemon I'd add some lemon zest.
