Prepare macaroni according to package directions. Drain macaroni well and rinse with cold water until pasta has cooled.
Meanwhile, in a large bowl, combine mayonnaise with chicken stock and salt and pepper to taste (about a teaspoon of each to start).
Add in drained pasta along with green pepper, radishes and onion.
Stir well until combined. Give it a taste to see if you would like more seasoning.
Cover with plastic wrap and store in refrigerator for at least 3 hours. Stir again before serving.
