Place bananas, pear (or apple), kale, orange juice, water, ice cubes and flaxseed in a blender. Pulse a few times, then puree until smooth, scraping down the sides as necessary.Advertisement
Choose organic kale when possible. Nonorganic can have high pesticide residue.
Look for ground flaxseeds (or flaxmeal) in the natural-foods section of large supermarkets or in natural-foods stores. Store in the refrigerator or freezer.
