Combine all —soy yogurt, frozen fruit, hemp seeds, flaxseed, oat bran, protein powder, vanilla, and lime juice—in a high-speed blender.
Blend on high until the mixture is completely smooth and creamy.
Pour into glasses and enjoy immediately for the best texture and flavor.
When choosing a vegan protein powder, opt for unflavored or vanilla varieties to complement the fruit flavors. If using a vanilla-flavored powder, you can omit the vanilla extract.
Garnish with a sprinkle of toasted coconut flakes, a fresh mint sprig, or a lime wheel to enhance the tropical vacation vibe.
