I never liked beet in smoothies although I love beets. After a few trials of errors, I settled on this concoction. A velvety smooth, rich reddish purple drink for breakfast. The key was to use cooked beets.
1 medium red beet (I cooked whole beets with skins in a pressure cooker for 8 minutes)
2 cups packed kale leaves
1/2 cup frozen strawberries
3/4 cup apple cider
1 Tbsp grated ginger
2 tsp apple cider vinegar
Put everything in a vita mix, and blend until smooth.
