Using the linzer cookie cutter, press down onto the bread and cut out 6 pieces WITHOUT the star center and 6 pieces WITH the star center. Be sure to cut the circles as close together as possible. You should be able to make 2 to 3 pieces per slice.
Using the leftover bread, remove the star cookie cutter and cut out as many stars as you can.
Slice the green apple down each side to create nice size pieces. Cut at least 3 circles with the linzer cookie cutter from the apple slices.
Spread peanut butter onto bottom circles, add strawberry jam or grape jelly onto the peanut butter, add an apple slice, and spread more peanut butter onto the bottom of the bread with the star cutout.
Add more layers by repeating step 5 if you so wish!
Serve and enjoy!
