Put 100 g Fat free cottage cheese, 115 g 0% Fat Free Greek yogurt, 1 teaspoon Dijon mustard and juice of 0.5 Lemon into a blender and blend until smooth.
Add the blended cottage cheese mixture to a bowl with 200 g Tuna, 1 rib Celery, 50 g Red onion, 5 g Fresh chives, 35 g Gherkins, 1 pinch Sea salt and 1 pinch Ground black pepper.
Mix well and serve.
Notes
We blended the cottage cheese and yogurt in a blender jug, but you could just put an immersion blender into the cottage cheese/yogurt container and blend it up to save washing up.
You can also leave the cottage cheese in curds if you prefer, and it does add some extra texture. We like to blend it all together to make a smooth dressing. You can mash it with a fork to leave a little bit of the lumps.
If you prefer a drier tuna salad with cottage cheese, then use a ⅓ less of the cottage cheese and yogurt.
For an extra burst of flavor, you can add a few splashes of hot sauce to the mixture. We like buffalo hot sauce.
