Croque monsieur w/ tarragon, sweet mustard salad + mango chutney

A classic for a reason, this sandwich can be found on menus all over the world. But how many are not up to scratch? This is as comforting as a hug from Nan. The tarragon vinegar and fresh tarragon make this sandwich spectacular. The mango chutney may seem like an odd pairing, but it really works. And a sweet mustard salad is the perfect addition.
