I have enjoyed this recipe for years.  I love Hellmans mayonaise and found this recipe on the back of the jar.  When Sister and I were catering full time we used this a lot.  People loved it and it was easy.  We served it with rosemary mashed potatoes, sauteed green beans, salad and yeast rolls.  I hope you enjoy it as much as we have. 

1/2 cup Hellmann’s mayo
1/4 cup grated Parmesan cheese
4 boneless, skinless chicken breast halves (about 1-1/4 lbs.)
4 tsp. Italian seasoned dry bread crumbs
Preheat oven to 425°.
Combine Hellmann’s Real Mayonnaise with cheese in medium bowl. Arrange chicken on baking sheet. Evenly top with mayonnaise mixture, then sprinkle with bread crumbs.
Bake 20 minutes or until chicken is thoroughly cooked
