Using a pastry brush, lightly coat a chicken breast with mustard on all sides. Place in bread crumbs and firmly press down. Turn and repeat until entire breast is coated with crumbs. Set aside and repeat with remaining five breasts.
Preheat oven to 350 degrees. Meanwhile, heat half the butter or olive oil in a 10-inch saute pan over medium heat for 30 seconds. Add 3 breasts and cook for about 2 minutes, until golden brown. Remove to a baking sheet and repeat with the remaining 3 breasts. Set baking sheet in hot oven for 10 minutes. Remove and cover to keep warm. Serve with Morel Sauce, if desired.
