Let me tell you something about a chili we recently made.
Lets say its friday night, ate the chili, and like you forgot it on the stove. Next morning put it in the fridge, and ate it saturday night. Woke up sunday morning to find the chili, again on the stove, warmed it back up and ate it for the Chiefs game.
We were fine.
We did however have stew meat instead of ground beef.
