Mr. Silver, we are oddly similar (in a good way). For portable protein I like raw nuts - almonds, filberts, walnuts, cashews, etc. If you have an insulated cooler you could bring yogurt, cottage cheese, etc. Raw carrots are a staple for me. I can eat raw broccoli and cauliflower to. A little ff dip is good with that but hard to do whilst driving. My fav? Raw sugar snap peas!

For a special I-feel-like-a-kid treat: core an apple and fill it with a mixture of peanut butter and raisins. Yummy!

And you're just a hair taller than me but you have a cooler car.....
