If you want to make these buffalo chicken stuffed peppers as part of your easy weeknight dinner meal prep, there are a few options: You can stuff the peppers and then place them in the fridge to be baked a few days later. Unbaked or baked they will last 3-4 days in an airtight container. You can fully cook the peppers and store them in the fridge. If you aren’t going to eat them within that time frame, freeze them for up to 3 months. Defrost in the fridge overnight and reheat the next day.
