Maple-Balsamic Chicken

I tried this because it was such a strange set of ingredients -- maple syrup, balsamic vinegar, and peanut butter. I don't know who thought this one up but I had to see if it was edible. Well it was way more than edible, it was delicious. I'm going to be making this often as the ingredients are all in my cupboard. That's sooooo convenient. It's easy to make and as I already said -- delicious. My only reservation would be that I don't think it's necessary to use chunky peanut butter. Creamy would work just fine.  

I used boneless chicken breasts instead. It took much longer than 5 min for the sauce to thicken. It was good and I would make it again.
