That looks like the standard tray that's used by a lot of frozen entrées sold in supermarkets these days. Maybe they just loaded up a bunch of those.On the CS today - some unique aspects in the flexible dining today. They have the flex meals plus a meat or veggie lasagna option which is completely different than the normal flexible meals - looked more like it had been prepared at a comissary and reheated - not the usual flex container. They also had the oven pride cafe car burgers and Hebrew National hot dogs available in the diner as well. The lasagna was pretty good - I should have taken a photo before eating but didn’t think too so there’s the finished container.
