This actually started out as Grandma Charlotte's recipe, and I think she started out with a potato salad idea from The Joy of Cooking.
1 pound spiral pasta
1 cup Wishbone Italian Salad Dressing Accept No Substitutes
13 ounces of white tuna in water
1/2 cup mayonnaise
1/2 cup of chopped celery
1/4 cup of chopped up sweet gherkins
Anything else you like in a summer salad: canned corn, fresh cooked corn, green pepper, red pepper
Cook the pasta according to the package
While it cooks, do any needed chopping.
Open and drain the tuna, then empty into a large mixing bowl and break it into small pieces.
Add the mayonnaise, celery, gherkins, and anything else you like to the tuna and mix well.
When the pasta is done, drain it, then instantly shake up the salad dressing and pour it on to the pasta, stirring well to spread it around. Let it sit for a couple of minutes for those flavors to blend.
Add the pasta to the tuna and again mix well.
Eat warm or chill and eat later.
