This one is so simple good(ish) for you and ingredients can be found in any good fruit store. (As if you would use a bad store)

Long wooden skewer
Melon Pineapple Banana
Butter syrup cocoa powder

Cut the fruit into even sized pieces.
Thread onto skewer, mixing fruit.
For the chocolate sauce, Butter, syrup and cocoa powder in a pan. Heat and boil just a little. Nice to add some brown sugar, vanilla perhaps a hint of instant coffee. Mix well serve warm – worth testing it will be the correct runniness at eating temperature. Adjust with water if required.
