For some reason, I really like canned tuna at the moment. On the basis that if something smells or tastes very good to you, or that you crave it, then it probably contains some nutrient that your body needs, I decided to go with it and make myself a tuna pasta salad.
To some cooked pasta shells I added a drained can of flaked tuna (well, most of one - the cats demanded their share!), a small can of sweetcorn, some halved cherry tomatoes and basil leaves. I think tomato and basil go very well with tuna. I debated adding some cucumber, but decided this was enough. No need for mayonnaise or other dressings, either.
