For the drive to the Gorge to see Coldplay today, my packed snacks include:

Antioxidant Trail Mix from Trader Joe's. It is the best trail mix ever, seriously.
Honey Bunches of Oats with Almonds
Mission Tortilla Chips (very salty, these)
An apple (Gala)
A few Dove chocolates (the 63% dark is my favorite)
Lots of bottled water

Pretty healthy but still tasty, I think.
