Unless it’s so tasty you eat all of it, how can eating food tempt someone to sin?
That’s addressed in Corinthians. Basically, eating the food is no sin, but the act of sacrificing the food to idols is a sin. If, by partaking in the eating of the food, you can be seen as approving of or endorsing the sacrifice, then you could be tempting others to engage in the idolatrous practice.
