fast, easy, healthy snack ideas:
~ can of chickpeas with a sprinkle of garlic seasoning (if you don't have time or equipment to open the can and drain the chickpeas there you can do that beforehand and keep this simple snack in plastic tupperware.)
~ hummus dip with baby carrots and celery sticks - you can make your own low fat hummus dip by blending chickpeas, water, and your choice of seasoning in a blender or just buy premade low-fat hummus.
~ small organic dry-farmed tomatoes make a yummy snack
~ fruit like grapes, cherries, peaches, an apple, pear, or banana are easy to pack; just make sure they're ripe
~ you can make a cold pasta salad or a cold bean salad and keep it in tupperware. Just have a spoon, fork, or spork ready to eat it.
~ you can pack a salad in tupperware although you'll want to keep it somewhere cool.
~ popcorn plain or with a healthy topping like nutritional yeast can be a healthy snack.
~ if you're making sure to eat something filling and healthy for your regular meals, you won't be that hungry later on.
Good luck! :)
