I spent two hours preparing lasagna yesterday. A beautiful, vegetarian lasagna. It wasn't quite done before I had to leave for a birthday party, so I turned off the oven and left it to sit until we got home, with the intention of putting it in the fridge. We arrived home late, went to sleep, and I only remembered this morning it was still in the oven! So, it was left out of refrigeration for about 15 hours. It was tightly covered with foil, sitting in the oven. Do I need to throw it out? Is it salvageable? What do you think?
