Jennifer Zwiebel, founder of The Kosher Hostess, had a sandwich like this in a restaurant years ago and has been trying to recreate it ever since. Its surprising combination of flavors and textures work wonderfully together. This simple, warm dish is perfect for a cool fall day, served as an appetizer or as a comforting meal with a bowl of soup or a light salad.

I’ve laid out a basic version of the recipe. Feel free to play with it to suit your tastes! Try different cheeses (Gouda and Swiss, or a combination of the two, are delicious options). Use apple or pear chutney instead of mustard for a sweeter variation. Try apple slices instead of pears. You can even try dried fruit—I made one sandwich with dried pears and it was delicious!

If you want to make an even healthier version of this meal, leave out the butter and make the sandwich in a toaster oven instead of a frying pan.
