Boil half pack of pasta al dente or more minutes if you want them tender (I usually use fusilli or farfalle as they are easier to boil and looks nicer in the plate).
Cool-down pasta.
In a bowl, mix 3 canned qualitative tuna, 3 chopped ribs of celery, 1 small chopped red onion, 1 canned green peas with the cooled pasta. Season with a pinch of sea salt if needed.
Pour the creamy home-made mayonnaise (or yogurt at your discretion) over the mixture and serve immediately, or save it for later.
