How to make: Banana and Greens Smoothie Step one: slice and freeze a banana for several hours Bananas make a terrific smoothie base, for the taste and the potassium content. By freezing, your smoothie will turn out even creamier! What else you will need: 1/2 cup orange juice 1/2 cup ice (optional) 1/2 cup oat milk (any plant milk will do) 1/2 cup arugula Blend everything but the banana first Now the remaining ingredients High in vitamins A, C, B9, and magnesium, arugula is used in many international cuisines, from an Italian pizza topping to South American saladS Slightly bitter, mostly sweet, a great way to start any day!
