I do not know what is in this cheese sauce and I agree with all the other reviews I've read online trying to post this so people know that it was indeed hard as a rock, unbreakable, and unusable upon opening the package. I thought maybe moisture had gotten into the cheese sauce packet so I put it in the microwave for approximately 15 seconds. I DO NOT KNOW WHAT IS IN THIS STUFF BUT DO NOT MICROWAVE IT AND I'M GLAD I DID BECAUSE I WILL NOT BE EATING IT. AFTER APPROXIMATELY 15 TO 20 SECONDS IN THE MICROWAVE IT'S SMOKED OUT MY ENTIRE KITCHEN AND LET OFF A CHOKING SMOKE THAT IS MORE THAN "NACHO" FLAVORING! I AM STILL COUGHING, MY CATS ARE STILL COUGHING, AND I FEEL LIKE WHATEVER WAS IN THE SMOKE HAS BURNED THE BACK OF MY THROAT. BOTH KITCHEN FANS IN THE BACK DOOR OPEN IT IS STILL SO BAD SMELLY IN HERE FROM THIS PACKET THAT AFTER SECONDS IN THE MICROWAVE TURN INTO SOMETHING ELSE. So glad this happened and I do not consume whatever these people put in their product!
