Sendameal heating
I received some meals and will serve the first ones tonight. They are in tv dinner trays with clear plastic and a cardboard sleeve. The heating instructions say to remove the cardboard sleeve only. So the plastic stays on (no vent hole) and I put it in the oven? Seems like I should poke a hole in the plastic or even remove it. It’s been about 50 years since I had a tv dinner and I can’t remember if I vented them.
