How long do weenies last in fridge after being grilled?

It depends on how the weenies were cooked and stored. If the weenies were cooked thoroughly and then stored in an airtight container in the refrigerator, they can last for up to 3-4 days. If the weenies were not cooked thoroughly, they should be consumed within 1-2 days. If the weenies were left out at room temperature for more than 2 hours, they should be discarded.
