Kim Kardashian -- I CAN'T STOP EATING .... CHALUPAS

Kim Kardashian was faced with a choice the likes of which haven't been faced since Sophie -- papas or paparazzi.

Kim joined her sisters for what was supposed to be a delicious lunch at Casa Vega in the Valley Thursday ... but the pesky pappers were blocking her entrance and wouldn't follow instructions to "MAKE A HOLE!"

As the smells of the fried burritos and chimichangas wafted to her waiting SUV, Kim made the hardest decision since agreeing to let Ray J really have his way ... She left.
