slice or chop watermelon and mozzarella into desired size/shape and add them to the bowl/plate you are serving from
drizzle olive oil and balsamic glaze over top and add flaky sea salt to taste.
*if you are assembling ahead of time, wait to top with olive oil, balsamic and salt until right before serving
*generally, I buy my balsamic glaze as it's an easy pantry staple to keep on hand for parties. however, you can also make your own by bringing 1 cup balsamic vinegar to a boil over medium heat. once boiling, reduce to a simmer and simmer until the vinegar starts to thicken and coats the back of spoon (about 10 min) be careful not to burn. glaze will continue to thicken as it cools.
