Ketosis has nothing to do with calories. It is solely dependent on the number of carbs you take in. MF limits are 80-100 carbs. If the carbs in the beans put you over that range, then yes, it could conceivably knock you out of ketosis. It was a very small amount so it probably didn't, but if you get into the habit of lots of bites, licks and tastes, then it can add up pretty quickly.
