1 grapefruit, peeled, seeds removed (reserve juice)
1 large sweet apple, cored and skin removed (I prefer honeycrisp)
2 cups spinach (I like to freeze mine to keep it extra fresh)
1 large ripe banana, previously sliced and frozen
2-3 ice cubes
Unsweetened almond milk, water or orange juice to thin (~1/2 cup)
OPTIONAL: 1/2 tsp fresh ginger, peeled and chopped
Add all ingredients to a blender (including reserved grapefruit juice) and blend until creamy and smooth. Add more liquid if too thick, ice to thicken, and banana or apple to sweeten. Serves 2.
