I'd be inclined to look at my nutrition tracker and see what i was most low on (fat, carbs or protein.. i also track calcium and iron) and choose my snack based on trying to fulfil the "shortage" areas. Since I'm typically lowest on protein (and, often, calcium) - I'd probably choose a snack like cheese or yogurt.
