• Toast bread.

• Meanwhile, wash and dry produce.

• Halve, core, and thinly slice apple.

• In a small bowl, combine mayonnaise, mustard, and a pinch of sugar.

• Spread one side of each bread slice with Dijonnaise. Top half the bread slices, spread sides up, with gouda, as much turkey as you like, and as many apple slices as you like. Top with remaining bread slices, spread sides down. Halve sandwiches on a diagonal. TIP: Refrigerate any leftover turkey in an airtight container for up to 1 week.

• Divide sandwiches between plates. Serve with any remaining apple slices on the side.
