Freeze leftover lettuce and spinach or just buy a big container and stuff into baggie and throw in freezer. Hitting baggie lightly on counter a few times will break it up.
Freeze bananas in baggies for smoothies - one banana to a bag. They break up easily.
Freeze grapes and other fruits (oranges, grapefruits) that you think could go bad in a few days - this will keep you from wasting food. It is cheaper to buy fruits and veggies on sale and freeze, if you have room, than buying the pre-frozen packages at store.
Make a fruit cocktail in a baggie and it will be ready to throw in blender. Sometimes I add a bag with oranges, grapes, strawberries, pineapple, and bananas. Just add your choice of protein flavoring and almond milk. We always use almond or coconut milk because we are vegetarians.
Don't overlook veggies like left over broccoli and asparagus - freeze them. They go great in sweet smoothies; kids will never know if you don't tell.
Take frozen squash or other congealed veggies and fruits out of freezer the night before and let them sit in frig. They will still be icy cold the next day.
Sometimes hubby is not ready for a smoothie when I am and sometimes, in an experimental stage, I keep adding ingredients until I have enough for 3 or 4 people so I put the extra in a Yetti cup. Most of the time the smoothie still has ice crystals the next day. They make great leftovers for a breakfast. Do drink within 24 hours of making and always stir before serving.
