If you're on the road and looking for a snack, pre-packed trail mixes can often be found in convenience stores, but beware their fat, sodium and sugar contents. Luckily, trail mix is a quick and easy make-at-home snack that will keep well in a storage container with lid. Combine granola, raw nuts and seeds, and dried fruits for a basic trail mix. Give it a touch of sweetness with dark chocolate chips, or if you want something with both crunch and spice, try adding wasabi peas. And don't forget the trail mix classic: GORP, which stands for good old raisins and peanuts. Change that up a bit, mixing 2 tablespoons of dried cranberries with 1 tablespoon of peanuts and you have a single-serving, 100-calorie snack.
