If one receive cooked food from a person that perhaps used ingrediants from a hechsher that one normally wouldn't eat is it bal tashchis to throw out the food?
With packaged, store-bought food it would be easier to simply give it away to a neighbor or friend. However normally home-made food is harder to give away to others so, consider in this case that that option is not available.
If it is bal tashchis, then what should the person do? Simply let it sit in their fridge until it's no longer edible?
