I'd say you were probably right to cook it off and put it in the fridge. Being a chef, I wouldn't recommend assembling something with different cooked and uncooked ingredients and letting it sit for a few days. Fridges only minimise the growth of bacteria, they don't stop it completely, so if you'd let the meat cool down and mixed that with uncooked cheese which could have a few nasties...well you get the point. Always make sure that when you cook something, let it cool for NO MORE than an hour and a half at room temperature, then put it in the fridge immediately. If you're reheating it, make sure when you cut into it that it's steaming hot all over.
