Measure out one cup of each of the ingredients (feel free to make your own swaps here) and add them to a large zip lock bag. Seal the bag and give it a shake until everything is well-combined.
Either bring the whole bag with you on your adventure or measure out the amount you need and store it in a smaller zip lock bag.
For school snacks or workweek snacks, divide individual portions of trail mix into separate airtight containers or ziplock bags or a reusable stasher.
If you're planning on keeping this as a delicious snack for home, store it in a glass jar such as a mason jar. Planning on making traditional trail mix for your next party as an easy snack? Serve it up in a large bowl.
Notes
For a crunchy, salty mix, use roasted salted nuts instead of raw nuts.
