This is another recipe of the latter & uses leftover roast beef in a tasty way to prove you need not become bored w/an excess of leftovers. *Enjoy*

Made this today for lunch. Two variations though, I did not have any wheat bread so I used plain white bread and I didn't realize that I was out of celery salt! Neither was a big deal. I made two sandwiches and ate them both! Needless to say I enjoyed both. Made for football pool 2010.

Great tasty, flavorful sandwich. I left out the celery salt. I agree with mommyof flour that the mayo mixture was great. A great lunch. Made for the win in Football Pool.

I made this for lunch today and my kids were very skeptical about it. They ate the sandwich but the younger two removed the orange slices. I on the other hand thought it was good. Its a different lunch thats for sure, but I liked the citrus with the beef. The mayo mixture was yummy and I'm already planning on using that on some "wraps" also this summer. I will make this again, but probably just for hubby and myself. Oh well, the kids don't know whats Thank you for posting. Made for Newest Zaar Tag 2008.
