Here's what happened: I bought one of those pre-cooked shepherd's pies from Costco. Not from their frozen meals section.... the ones that they make and keep in the coolers by the meat. But those are huge, and I live alone, so I only heated half, and intended to cover the other half with tin foil and freeze it.
Now, I forgot it on my counter all night. Found it this morning. My house was about 18? degrees C all night. On one hand, it was already cool when I left it out, so that's probably not good. On the other hand, it's all pre-cooked ingredients (beef, peas, corn, potatoes, and cheese on top). It smelled ok, and I nibbled a bit of beef and it tasted fine, but I still want to be sure. Would you eat it?
