How to Make This Recipe
Step 1 – Prepare the Ingredients
Start by dicing the celery and mincing the red onion. If you’re using fresh herbs, chop the parsley and dill as well. Next, open the cans of tuna and drain most of the liquid to avoid a watery salad.
Step 2 – Mix the Salad
In a large bowl, combine the drained tuna, Greek yogurt, diced celery, minced red onion, Dijon mustard, fresh herbs, sea salt, and black pepper. Use a spoon to mix everything together until it’s fully combined. Make sure to break up the tuna a bit so it’s evenly distributed throughout the salad.
Step 3 – Taste & Serve
Once mixed, taste the salad to see if it needs additional seasoning. You can adjust the salt, pepper, or mustard according to your preference. Serve it right away for the freshest flavor, or store it covered in the refrigerator for later.
