Whisk the Colavita Vinegar, sugar and kosher salt along with 1 cup water in a small bowl until the sugar and salt dissolve.

Place onion in a jar and pour the vinegar mixture over the onions.

Allow the onions & vinegar mixture to sit at room temperature for 1 hour, then cover and place in the fridge for up to 2 weeks.

Drain onions before using.

Place all the ingredients in a blender or food processor and process until smooth.

Cook the rice according to the instructions on the package. When the rice is cooked and has absorbed all the water, add 1 tablespoon of Colavita Balsamic Vinegar and 1 teaspoon of Colavita Extra Virgin Olive Oil. Mix well. Cover the rice with a lid and steam for 5 minutes. Uncover and fluff with a fork.

Place the cooked beets in a food processor and chop until you have pea-sized beet pieces. Add the black beans and prunes to the beets in the food processor and pulse until just combined.

Remove the beet mixture to a large bowl and add the cooked rice and the rest of the ingredients.

Cover the mixture and refrigerate for at least 1 hour, though can be overnight.
After this time, form into burger patties. Place the patties on a cookie sheet lined with parchment paper.
