In a small pot combine diced apple, maple syrup, vinegar, powdered ginger, and 2 tablespoons water. Set over high heat and once the mixture comes to a boil simmer on low heat for 5 minutes. Drain apples (discard liquid) and mash with the back of a fork to form a coarse paste. This is your "shortcut" apple chutney.
Spread the chutney over two slices of the bread. Top with a layer of Brie and turkey (if using). Add remaining two bread slices over top.
Either in a medium-sized saute pan over medium heat or on a griddle set to 375 degrees F add two generous pats of butter. Once the butter melts place the sandwich in the pan/griddle and cook on each side for 2 to 3 minutes or until golden brown. Slice and serve warm.
