Shout out to my What's Cooking Sister Erin, not to be confused with my real sister Erin who is also great cook. I got this recipe from Erin's blog and it was delish!

1/4 cup butter, melted
2 tablespoons Dijon mustard
3/4 cup dry bread crumbs
1/4 cup grated Parmesan cheese
2 boneless skinless chicken breasts

Combine butter and mustard in one bowl, and bread crumbs and cheese in another. Pound chicken breasts to half inch thickness to allow quicker cooking. Dip each chicken breast into butter/mustard and then into bread crumbs/cheese. Place in an ungreased baking pan and bake at 375' for 25 minutes or until done.
