I wish I had remembered to take a picture, but when you have a toddler who is ready to eat sometimes that's all that seems to be important!
I modified this recipe tonight from a few I found on allrecipes.com.
The Dijon really added the extra boost of flavor that made this a keeper!
4 boneless, skinless chicken breasts
French fried onions, crushed
4 slices provolone cheese
Spray baking sheet with cooking spray. Place each piece of chicken on sheet. Spread a fine layer of Dijon on the top of each chicken breast. Top each chicken with a generous topping of fried onions -- press them gently into the Dijon so they "stick".
Bake at 350 for 30 minutes or until juices run clear. Top each chicken with a slice of cheese. Bake for additional 5 minutes or until cheese is melted.
