Make a pocket in each slice of bread and set aside. In a medium bowl, mix together the marshmallow creme and hazelnut spread until smooth, then stir in the chocolate chips. Fill each pocket with some of the spread.
Whisk together the half-and-half, honey, cinnamon and eggs in a shallow dish. Dip each bread slice in the batter and set aside.
Lightly spray the grill pan with cooking spray. Grill the French toast until well-marked and crisp, being careful not to burn it, 2 to 3 minutes on each side.
Meanwhile, place the strawberries cut-side down on the grill pan and grill until slightly cooked, 1 to 2 minutes. Set aside.
Transfer the French toast to individual plates, drizzle with caramel, shave over chocolate, top with grilled strawberries and serve alongside the warm syrup.
