Tuna and Quinoa Salad with Artichokes - Dairy Free. A richly flavoured summer salad filled with mediterranean ingredients, and made with quinoa rather than couscous which would be typical of tabbouleh. Quinoa is gluten free and I absolutely love it. It makes a great base for salads like this one! You might expect to find cheese such as feta in this recipe, but not here on my blog!
