Cut 1 1/2 pounds mixed tomatoes into wedges; season with salt and pepper. Cook 3 Tbsp. balsamic vinegar and 2 tsp. brown sugar in a small skillet over medium heat until reduced by half, about 3 minutes. Remove from the heat and whisk in 2 Tbsp. olive oil. Drizzle over the tomatoes; top with snipped chives and basil. Enjoy!!
