I agree with teresamay. I would look up just the bagel and subtract the amount of carbs for that from the rest, and you should have the correct # of carbs for what you ate. You should be okay, I have had the steak egg and cheese bagel my self, its one of my faves, but as long as you removed the bagel, you should be fine. the sauce part is mostly mayo, and the grease from the steak, of course, but that is what I would do. A bagel about the size of what you had is about 50 carbs, so its not too bad at all.
