Balsamic Double Onion Roast Beef Sandwich

Who is your favorite Top Chef? Well mine is Fabio Viviani. And after eating this sandwich which is from his upcoming book, Fabio's Italian Kitchen, I am guessing he may be my husband's favorite too!

We decided to put the sandwiches on the panini press. Excellent idea. We also made a horseradish spread in place of the dill pickles. Roast Beef and horseradish always go together.

And what's that on the side of the plate? Fries! Yes 5 Minute Frozen French Fries. Not something we have very often but one of our favorites. They taste just like fast food fries. Love them!
