Season with salt and pepper.

  3. Preheat skillet or panini press. Grill sandwiches over low heat until bread is toasted and cheese is melted. Cut in half and serve.

I made this for my husband and I and was a bit disappointed since I love all the ingredients listed. I wasn't a huge fan of the pickles on there so ended up picking them off. I'd make it again, just without the pickle.

Hello Mary, we had these sandwiches yesterday and they were soooo good - that if I had my way I'd have it again, today! The pickles were optional for most of the people - and instead they used crushed red pepper flakes just a pinch mixed in with the Dijon mustard! Awesome!! Thanks for posting, Manami :)
