Sliced fresh mushrooms are best, although you can use canned. Brown
bell pepper, onion, and garlic in oil in skillet. Also brown mushrooms, if
using fresh. Place whole chicken in crockpot; add seasonings and
vegetables, topping with vegetables from skillet. Add wine. Cook until
done. Remove chicken to warmed platter (in 200-degree oven). Add water
to cornstarch and salt and stir to a paste, then add to crockpot mixture
and cook until slightly thickened and bubbly. Spoon sauce over chicken.
