Spread the pretzels on the baking sheet. Using two lightly oiled teaspoons, place 5 ml (1 teaspoon) of caramel in the centre of each pretzel. Place a pecan half on the caramel, pressing lightly. With a spoon, drizzle the chocolate over the pretzel bites. Let cool completely, about 30 minutes or until the chocolate is firm. Store in an airtight container at room temperature for about 1 week, separating each layer with a sheet of parchment paper.
