Here's what you need:
1/2 cup shredded Gruyere (or your favorite) cheese
3 slices Angus Roast Beef, sliced for sandwiches, they are about 8 - 10" long ea.
1 Ciabatta Roll
Mayo - The good stuff (Best Foods or Helmans NOT Miracle Whip)
Dijon or yellow mustard
Ingredients for both sandwiches.
The left sandwich is spread with Dijon and mayo, the right has yellow mustard and mayo.
First place 1/2 the cheese on each side of the roll.
Then place the roast beef on one half.
Place the top on and make sure all the yummy cheese stays inside.
I have a Breville Panini Press that fits two Panini's front and back. Press for 5 minutes.
They are super simple and I'm going to try Ham, Gruyere, Dijon/Mayo, and sliced pears next.
