For a fresh fruit option(where serving immediately from the freezer is not an option): Make a solution of water and lemon juice(about 1 tbsp lemon juice in 2 cups of water). Dip the banana slices in the lemon juice solution. Assemble the fresh strawberry, banana dipped in lemon juice and water and fresh pineapple on the popsicle stick as desired and place in the fridge for at least 30 minutes. When chilled, dip in melted but cooled chocolate and place on a lined baking sheet and place back in the fridge. Once the chocolate is set, these can be removed from the fridge, but should be served within a few hours.
