Reduce vinegar by pouring ½ cup of pomegranate balsamic vinegar (link to recipe in recipe notes) to hot saucepan. Cook on medium-medium/high heat, stirring occasionally, until ⅓-1/2 of vinegar remains. Remove from heat and add 1 tablespoon of olive oil to reduced sauce. Stir together, and set aside. (if dressing hardens, whisk in more pomegranate balsamic vinegar, adding just a bit at a time. This will thin it out)
Add ½ c uncooked butternut squash cubes to a microwave safe bowl with ¼ cup water in it. Microwave on high for 4-5 minutes, or until butternut squash is soft (test by piercing a fork into one cube. If it goes in and comes out easily, it's done).
Heat cast iron skillet or large saucepan over medium/medium high heat. Once pan is hot, add 2 teaspoon oil, and then ½ cup cooked cubed butternut squash. Season with a pinch of salt and pepper. Stir and flip butternut squash just 3-4 times so each side gets crispy. Squash is done once sides are crispy. Remove from pan once crispy.
Add chopped kale to pan, and cook until softened and kale begins crisp up. Stir kale often to avoid burning. Remove from pan.
Add butternut squash, cooked kale, 1 tablespoon of each pistachios and pomegranate aerils (optional) to a plate. Pour pomegranate balsamic salad dressing over salad.
Serve with pomegranate balsamic marinated pork loin or pork chop. Recipes in notes section.
