Matcha is a powdered green tea that’s high in antioxidants; you’ll find it in most large natural grocery stores or Asian markets. If you can’t find matcha, steep 4 green tea bags in 1⁄2 cup boiling water for 3 minutes. Remove tea bags and let liquid cool, then add tea to smoothie; reduce rice milk by 1⁄2  cup.
3 cups baby spinach
2 cups rice milk
1 medium avocado, peeled and cut into chunks
½ cup green grapes
2 Tbs. matcha green tea
2 Tbs. grated fresh ginger
1 Tbs. agave nectar, optional
Blend all ingredients in blender until smooth.
