Add the pasta to salted boiling water and cook until al dente (roughly 8 minutes, depending on pasta shape).
Roughly chop the celery, cucumber, pepper into similar size pieced and finely dice the fresh parsley.
Prepare the dressing in a small bowl, whisk together the mayonnaise and lemon juice until smooth. Season with salt and black pepper to taste.
Drain the pasta and run under a cold tap to help cool the pasta faster and transfer to an extra large bowl.
Finally, add the chopped celery, pepper, cucumber, chopped parsley, tinned sweetcorn (drained), tinned tuna (drained) and the mayonnaise dressing along with a pinch of salt and pepper and mix well to combine.

Because there is mayo in the dressing, it could change the texture and taste. If you are able to freeze before adding the dressing, it will freeze much better. Simply let it thaw in the fridge before enjoying.Tip 1: Make sure to rinse the pasta in cold water as soon as you drain it. It will help the pasta to cool quickly and removes extra starch, both keeping it from becoming clumpy or mushy.Tip 2: This cold tuna pasta salad recipe is a great one for variations. Try using whatever veg you have on hand.Tip 3: If tuna isn’t your jam, you can swap for canned chicken, sausage, pepperoni, or tofu.
