Step 1

Cook pearled couscous according to the package. Once cooked, rinse under cold water. This will prevent the couscous from sticking together as it cools. Drain well and place couscous in a mixing bowl. Add 1 tablespoon olive oil and mix well.

Step 2

While pearled couscous is cooking, add all lemon vinaigrette dressing ingredients to a bowl. Mix well to combine and set aside.

Step 3

Add castelvetrano olives, shallots, flat leafed parsley, dill, and tuna to the bowl and mix well to combine. Add dressing and fold the mixture with a spoon. Place in refrigerator for 1 hour to allow flavors to meld.
