Place the tomatoes, undrained in the bowl of a food-processor or blender and pulse till chunky.

Pour the tomato puree into a small sauce pan. Add brown sugar and stir. Heat the tomatoes over medium high heat till they begin to boil, then reduce heat to a simmer and let tomatoes reduce down till you have a thick "paste". About 10-15 minutes. This should reduce down until you have just over 1/2 cup.

In a small bowl, combine the tomato reduction with Balsamic vinegar, olive oil and water. Whisk together and then add a dash (or more) of sriracha, dried oregano and salt and pepper to taste.

Serve immediately or keep tightly covered in the refrigerator for up to one week.
