Microwave the jam in a microwave-safe bowl until loosened, 20 to 30 seconds. Stir in the mustard; set aside.
Heat 1/2 tablespoon butter in a large nonstick skillet over medium heat. Add 1 crepe; stack 2 slices each ham, turkey and cheese on one half of the crepe. Cook until the crepe just starts browning on the bottom and the cheese starts melting, 1 to 2 minutes. Fold the crepe in half over the filling using a spatula, then fold in half again to form a wedge. Flip the wedge and cook until the bottom is browned, about 30 seconds. Transfer to a plate. Repeat to make 3 more crepes. (Remove the skillet from the heat between batches if it gets too hot.)
Toss the greens and frisee with the olive oil and a pinch each of salt and pepper. Serve the crepes with the raspberry mustard and salad.
