Store leftovers in airtight containers to keep your sandwich fixings fresh for days. The chicken and peppers stay tender and ready to reheat real good. Pop ‘em in the fridge if you plan to eat within 3-4 days. Reheat with a quick cover in microwave or on stove skillet to keep that cheese melty. Freeze any extra portions by wrapping thoroughly in foil and placing in freezer bags. They defrost nicely when you’re craving a quick meal later. For the sausage rolls, keep 'em separate if you can, that way they won’t get soggy while you store chicken mixture. Just toast rolls fresh before serving next time.
