I don't know what the ingredients are in that Asian salad, but with 12 grams of sugar (without the dressing, even!), I would avoid it. Why is there sugar in the salad in the first place, anyway?
Since you'll have a cooler, why don't you just pack your own salad makings in separate containers, and mix yourself up a healthy OP salad when you stop to eat? You could add things like roasted chickpeas, lowfat cheese, and nuts to jazz it up. As for other food ideas, you could take along yogurt, deli meat and cheese wrapped around celery sticks, raw veggies with hummus or ranch dressing for dipping, and string cheese. If you are on Phase 2, you could also take along fruit such as apples and grapes, and make sandwich wraps with ww pita or flat-out bread.
