Place spinach, cucumber, and celery into blender. Blend until smooth. The cucumber should provide enough liquid, but if not, add a little water.
Add the pineapple, papaya, ginger, and lime juice. Blend again until completely smooth.
Serve immediately or refrigerate in jars with tight-fitting lids for up to 2 days.
To turn this into a meal replacement smoothie, add 1 scoop of homemade protein powder which adds clean, plant-based protein and healthy fats. Most protein powders have gums, sweeteners and artificial flavors that can cause gut issues that lead to bloating. Stick with homemade protein powder and you'll be good to go!
