This looked good so I'm making it tomorrow but here is the recipe if anyone else wants to try it. I think you could use cabbage instead of bok choy too.
1 lemon (1 tsp. shredded rind, juiced)
1 1/4 lbs. boneless chicken thighs or breasts
1 Tbsp. olive oil
salt/pepper/thyme
8 oz. baby carrots or 1 cup chopped carrots
12 oz. chicken gravy
1 Tbsp. Dijon-type mustard
2 heads bok choy
Season and saute chicken until brown in a dutch oven. Add carrots, gravy and 1 1/2 cups water, Stir in mustard. Bring to a boil, place bok choy on top and simmer for about 10 min. Add lemon juice. When serving, sprinkle lemon rind on top.
