Some McDonalds have actually started offering a "protein meal," which is two burger patties with cheese, no bun, a side salad and a drink. If yours doesn't have that, try two double cheeseburgers with no ketchup and no bun (approx. 6-8 carbs for two). They can put it on a pancake plate or in a cardboard box for you, and you can eat it with a knife and fork. I probably do this at least once a week. And only $2!
