Chicken Rice Tetrazzini with Mushroom Gravy and Mustard Crumbs

I ate mushrooms for the first time with this recipe and really enjoyed them!  This was such a yummy recipe that made excellent lunch leftovers. 

You spread uncooked rice in a baking dish and top with chopped rotisserie chicken. 

The mushroom gravy consists of softened mushrooms cooked in olive oil, 2 Tbsn of flour, 1/2 cup white wine, 1/2 cup milk, 2 cups of water, 2 Tbsn parsley, and salt and pepper. 

The crumbs on the top are rice cereal crumbs, 1 Tbsn Dijon mustard and 1 Tbsn parsley.
