The first time I made this, I asked Tim to get me some whole-grain mustard at the store... he was confused, so I clarified by describing the mustard as "the one with all the tiny balls in it." That seemed to work for him.
I've made this chicken recipe a bunch of times and it's really tasty and easy. Made even easier if you use chicken tenders like I did... they don't take very long to cook. I used sage from our rooftop garden. I like the flexibility of this sauce- you can make it as is, or you can splash some cream in. Mmm.
Served with roasted potatoes with garlic and rooftop rosemary (the potatoes were fresh from the soil as of today... picked by yours truly at Amy's CSA farm). Also, roasted broccoli with garlic, red pepper flakes and lemon juice.
