Build Sandwich: Take 2 slices whole wheat bread and lay flat next to each other. On one side, add sliced cheese and ensure entire piece of bread is covered. On the other slice of bread, take about ½ tablespoon butter and spread evenly over entire piece. Spread 1 tablespoon boysenberry jam on top of the butter. Place 6 fresh basil leaves on top of cheese. Take the piece of bread with the jelly on it and flip it over on top of the cheese so that the jelly and the cheese come together. Take another ½ tablespoon of butter and butter the outside of one of the pieces of bread.
Cook: Pace the sandwich, butter side down, in the skillet. Reduce heat slightly. Watch carefully and ensure bread is not burning. When cheese starts to melt (probably after 3 minutes or so), butter the top side of the sandwich with butter (carefully - don't burn yourself!). Then flip sandwich over. Continue to watch carefully and remove when cheese is fully melted (probably another 3 minutes or so).
Serve: Set on a plate and enjoy immediately. Garnish with sweet basil.
