When I was younger, one of my favorite foods in the whole world was a mayonnaise saturated tuna pasta salad.
Now that I'm older, I still like my tuna pasta salad, but with less pasta, more (grilled) veggies, and a tasty lemon herb dressing instead of mayo.
How to make the BEST tuna salad recipe
Since tuna is the most important ingredient in a tuna salad recipe, it must be of the highest quality. Obviously, the freshest, in-season veggies should be used for grilling too.
You all know I'm all about wild and sustainable when it comes to my seafood and canned tuna is no different.
Wild Selections proudly produces it’s wild-caught tuna from ocean sources that are certified sustainable to the Marine Stewardship Council (MSC) Standard.
This standard ensures the fish stocks are healthy, well managed, and plentiful. Each product can be traced to where it was caught too.
I used Wild Selections Solid White Albacore Tuna in Water for this recipe and in each can was one perfectly packed, seasoned filet.
The tuna is also minimally processed, non-GMO project verified, and made with simple ingredients. Just white tuna, water, and salt.
It's seriously the cleanest tasting albacore tuna I’ve ever eaten right out of a can.
A great grilled vegetable salad for any occasion
Grilled vegetables are super delicious and super easy. Any chance I get to make char-grilled veggies, I do. So, it was a great excuse to put them in this salad.
This salad recipe is such a great make-ahead meal because the flavors actually get better as they sit for a few hours or even overnight.
It's an easy, tasteful side dish with the bright and boldness of the lemon vinaigrette marinating the grilled veggies, couscous, and tuna.
No mayo also means it's one of the best salad recipes to bring to a cookout, BBQ, or picnic too!
Additionally, Wild Selections pays it forward by donating 13 cents from the sale of each can! It all goes to the World Wildlife Fund's efforts on protecting marine life and expanding sustainable fishing practices. Eat your tuna and help give to a charity too!
So grab the grill and enjoy this Grilled Vegetable Tuna Salad Recipe all spring and summer long! Please let me know in the comments below how you liked it too!

OMG THIS DISH and those GRILLED VEGGIES bring me back to summer vacation during school! I'd go home and spend the months with my family/parents and my dad is the GRILL MASTER and would ALWAYS grill up the goods like what you have up there. UGH! Now I am yearning for a grill so bad!!!!
Karrie

This ain't yo average tuna salad, that's for sure! Love this modified, healthier version with all those delicious, perfectly grilled veg. Roasted and grilling and my fave way to prepare them. We always stock cans of tuna for quick snacks and lunches (had some today, actually, on a salad). Definitely gotta add this salad to the list of things to try - perfect for lunch or (when the weather warms) bbqs. XOXO
