Yes
I've done this for years, but with baguettes.

Home from supermarket - chop off ends and eat with a bit of butter - cut remainder in half, slice open and stick in freezer.

Every morning, frozen half baguette out of freezer, add butter and filling, take to work, eat at lunchtime. Today - roast beef, lettuce and mayo. Luvverly.
