Grill a new take on chicken breasts with sharp Cheddar, mustard-mayo, mushrooms and sourdough bread.
SAVE ON THIS RECIPE!
For a flavor change, try using Swiss or Monterey Jack cheese instead of the sharp Cheddar.
Stop at the deli to pick up a mixed-fruit salad or an Italian vegetable salad to serve with these hearty open-face sandwiches.
