Caprese Sandwiches

In a small sauce pan, add the vinegar, sugar and chili flakes. On medium-high heat, bring to a boil, stirring often. Reduce the heat to a low simmer. Continue stirring and cooking until the liquids have reduced by half and take on a thick, syrup consistency. Be sure to watch the reduction closely as it can burn quickly. Transfer to a bowl and allow to cool.

Slice each of the toasted rolls in half. Place half of the basil leaves on the bottom piece of bread and top with a few slices of cheese. Drizzle some of the balsamic vinegar reduction over the mozzarella and top with slices of tomato. Lightly sprinkle sea salt over the tomatoes and place the other 1/2 of the roll on top.
