Instructions
Make the prune pureé
Combine the prunes and water in a blender. Pulse to combine, then blend until smooth, pourable consistency forms, scraping the sides if necessary.
Store the purée in an airtight container in the fridge for up to 4 weeks.
Make the Teriyaki Sauce
Combine all of the ingredients in a saucepan over medium heat and bring to a simmer. Simmer the sauce for 10 minutes until reduced and slightly thickened.
Make the Beef Stir Fry with Winter Vegetables
Place the beef in a bowl and top with 1 tablespoon of the prepared Teriyaki sauce and sprinkle with black pepper. Stir to coat, then set aside to marinate while you prepare the rest of the ingredients.
In a large, deep sauté pan or wok, heat 1/2 tablespoon oil over medium-high heat. Once the oil is hot but not smoking, add the beef.
Cook until the beef is browned on all sides and fully cooked through, about 4 minutes. Remove the beef and any juices that have collected in the skillet to a plate and set aside.
Heat the remaining 1/2 tablespoon oil. Add the vegetables. Cook for 4 minutes, or until slightly softened and lightly browned. If the pan starts to dry out before the vegetables have softened, add 1-2 tablespoons of water.
Add 1/2 cup of the Teriyaki sauce to the pan. Stir to coat adding more sauce if desired. Add the beef and any juices that have collected on the plate back to the pan. Stir and warm for about a minute just to reheat the beef.
Serve immediately with sesame seeds if desired and extra Teriyaki sauce on the side for drizzling.
