Crunchy Onion Chicken

Just a slight twist from the recipe found on the French's fried onion package. 

4 boneless skinless chicken breasts
1 c. French-fried onions (cheddar or original)
1/4 c. spicy brown mustard or dijon mustard

Coat chicken with mustard, then roll in crushed onions. Place on a foil-lined baking sheet. Bake at 400 degrees for 20-25 minutes or until chicken juices run clear.
