Place all 4 slices of bread out on a work surface. Add 3 slices of Camembert to each piece. Top 2 slices of bread with the ham, doubling the ham over if necessary so it doesn’t stick out beyond the bread. Place the pear slices on the other 2 slices of bread. Place the slices of bread with the cheese and ham on top of the slices of bread with the pear and cheese.
Heat the oil in a large skillet over moderate heat for about a minute. Add the sandwich and use a can of beans or a full tea kettle to weigh the sandwich down (The idea is to press the sandwich). Cook 2 minutes and gently flip the sandwich over, press it down again, and cook another 2 to 3 minutes, or until the bread is golden brown and the cheese is melted and bubbling.
For the bread we suggest using multi-grain bread, but you can also use slices of a crunchy baguette, ciabatta, sour dough, or pre-sliced rye, white, or pumpernickel.
