The reason you are supposed to cook the lunch meat is because it is prone to Listeria, which is a bacteria that can cause serious illness. Since you already cooked the meat in the oven, the bacteria (if it is on the meat) has been killed. Same reason why we can't have soft cheeses (unpasteurized).
Yea the meat pie has salami, pepperoni, and ham....like I said it was baked but then put in the fridge cuz I like it cold! Mmmm
I was told even cold cold cuts, like ham and turkey, especially fresh ones, are ok to eat, just to avoid bologna, salami, pepperoni. But if you're already cooking it, I think it's definitely ok to eat cold. Good luck!
