Maple Dijon Chicken

I found another chicken recipe that my family really liked.  I think I found it on Pinterest, but not sure.  I need to keep better track as to where I find my recipes :-)

Maple Dijon Chicken

4 - 6 boneless, skinless chicken breasts
1/2 cup dijon mustard
1/4 cup maple syrup
1 Tablespoon red wine vinegar
Salt, pepper, garlic powder
Rosemary

Preheat oven to 400 degrees.  Place chicken in a 9 x 13 baking dish sprayed with Pam.  Sprinkle chicken with salt, pepper and garlic powder to taste.  Mix the mustard, syrup and vinegar in a bowl or cup and pour over chicken.  Sprinkle rosemary on top.  Bake about 45 minutes until done.
