The cilantro pesto really makes this sandwich different. This is from Cuisine at Home magazine, and it was a huge hit at our house. Luckily, this made enough of the pesto to make the sandwiches twice!
Mix mayonnaise, chipotle puree, and sugar in a small bowl.
04Spread each slice of bread with butter on one side. Spread cilantro pesto on the other side of two slices and top with cheese and chicken. Spread the other two slices with the mayo mixture and place on top of the chicken, butter side up. Toast in Foreman grill or in a skillet with a weight on top. (Cook over medium heat. When first side is browned, flip over and cook the other side, weighting again.).
