Peel the citrus, slice into smaller pieces if using the Navels – or pull apart segments if using the clementines. You want small pieces that are easy for blending.

Add the non-dairy milk, protein powder, oranges, and zucchini to a blender and blend from low to high until mostly smooth.

Add in all the remaining ingredients and blend until thick and frosty. You want to make sure you fully blend the citrus so that it becomes smooth and silky without and pulp or rind bits. Keep blending until you see a smooth swirl in your blender. If needed, add a splash of non-dairy milk or another liquid like fresh-pressed orange juice.

Pour into serving glasses and serve with a fresh citrus garnish!
