Easy to Make Low FODMAP Tuna Macaroni Salad

Just like our mash-up of macaroni salad and coleslaw in our Macaroni Slaw Salad (one of my fave creations of Summer 2018), this Tuna Macaroni Salad combines canned tuna and cooked macaroni.

It is great for a great lunch or snack dish that we have found is very welcomed at cookouts and potlucks.

Read our All About Canned Tuna article for some background information on buying canned tuna; they are not all the same, and as always, we want you to buy the best ingredients as possible to get the most delicious – and low FODMAP – results.

This Makes A LOT!

This recipe makes a lot of Tuna Macaroni Salad; enough for bringing to a potluck and feeding a crowd. You can halve the recipe, if you like. 

I based it on a 12-ounce (340 g) box of pasta, as I have a pet peeve about having half-used pasta boxes leftover, but you might feel differently.

Al Dente? Not Always

For this Tuna Macaroni Salad, which will be refrigerated for storage, cook the pasta a little softer than al dente for best results.

The pasta salad is very lightly seasoned. It is meant to be mild and appeal to kids, adults, FODMAPers and everyone else.

We love this for a take-to-school or office lunch. Make sure to place a cold pack in your lunchbox or bag.
