I keep these in the freezer all the time so I will have something for that unexpected guest.

NOTES : Part breads may be made ahead of time. Assemble and place on baking sheets and freeze. Remove to heavy-duty zip-top bag and store in freezer until ready to use.

Pepperidge Farm makes good little party breads. I aso vary the recipe by using mozzarella instead of cheddar, pizza sauce instead of mayo. and chopped pepperoni in place of green onion-good for the younger folks.
Another would be Mex. style- refried beans, taco sauce and Monterey Jack cheese.
