If using fresh pineapple and banana, peel and chop them into chunks. For a thicker, creamier smoothie, freeze the fruit chunks for at least 2 hours beforehand. Measure out all other ingredients.
Add the pineapple, banana, almond milk, turmeric, chia seeds, cinnamon, black pepper, and optional ginger and yogurt to a high-speed blender. Secure the lid tightly.
Blend on high speed for 45-60 seconds, or until the mixture is completely smooth, creamy, and has a uniform vibrant yellow color. Stop and scrape down the sides if necessary.
Taste the smoothie. If you prefer it sweeter, add the optional maple syrup or honey and blend for another 5-10 seconds to incorporate.
Pour the smoothie into a clear glass. Sprinkle an additional 1/2 teaspoon of chia seeds on top for garnish and texture. Serve immediately with a straw.
