You can get a heart attack just reading about it: A baked ham and Swiss sandwich soaked in rich cream sauce. But La Madeleine's Croque Monsieur, which is French for "Mister, you're going to croak if you eat this," is worth the year or two it will take off your life. All the main ingredients work perfectly together; the ham doesn't overwhelm the Swiss, which co-exists peacefully with the sauce, which seeps just right onto the warm bread. Like most of La Madeleine's fare, the Croque is a little pricey, but, then again, it's also filling enough to tide you well past the dinner hour.
