If acai is unavailable, use more frozen mixed berries. For the swirl, substitute dragon fruit with ripe mango or raspberries. Opt for unsweetened acai and plant-based milks to manage sugar. Boost protein with a scoop of protein powder or nutrients with a handful of spinach. Store frozen fruit in airtight bags to prevent freezer burn. Use pre-cut frozen fruit to save time. Prep the dragon fruit swirl up to 3 days ahead in the fridge. Avoid adding too much liquid; if your bowl becomes too soupy, add more frozen fruit or ice cubes to thicken it. Avoid over-blending to prevent warming the ingredients.
