I improvised this tonight, and it turned out remarkably well.
1/3 cup frozen aronia berries
2 cups frozen watermelon chunks
1/2 avocado
1 cup baby kale
1 cup plain Greek yogurt
1 Tbsp chia seeds
1-1/2 cups unsweetened vanilla almond milk
1 scoop berry-flavored vegan protein powder
1 kiwi, peeled and diced
Blend for 3-5 minutes, or until smooth. Makes 3-4 servings.
