Cut the pineapple slices into cubes. In a skillet, melt 1 1/2 tablespoons butter (about 20 grams) and sauté the pineapple cubes with the vanilla sugar packets. Cook over medium heat, stirring occasionally, for 15 minutes. Remove from heat and set aside.

Cut the crepes in half. Fold in the rounded edges of each crepe half.

Place some pineapple cubes at the bottom of each crepe half, sprinkle with grated chocolate, and fold to form a samosa shape. Repeat to make 14 samosas.

In a skillet, melt the remaining butter and cook the samosas for 2 minutes on each side, until the chocolate melts and the samosas are crispy.
