The LC whole wheat is what made you hungry. Intense hunger is indicative of an insulin spike. If you're in ketosis, you shouldn't be hungry.

My best advice would be to try to plan a little better in the future. Keep whole foods on hand (HB eggs, leftover meats, etc.). If you're in a situation that you can't be near a fridge, take a small cooler with you, to keep foods cold.

But just for today, look for a protein source to try and squelch the hugner.
