Slice biscuit and toast in oven for 5 minutes until lightly browned. Or lightly toast bread.
Warm hot ingredients in the microwave. I place everything on one plate and heat it up for 1-2 minutes.
Remove bottom of biscuit from oven and layer warm ingredients. Top with cheese.
Return to oven for about two minutes or until cheese is melted.
Remove both halves of biscuit or both slices of bread from the oven. Smear mayo and cranberry sauce on the top half.
Put sandwich together and serve immediately.
Notes
You can use any combination of hot and cold leftovers. Just keep the hot ingredients on one side and the cold on the other.Serve with additional leftover side dishes.
