In my opinion, tv dinners are too small, and probably loaded with sodium and preservatives, but I do buy one or two occasionally. Even though the trays are now made of cardboard, they work in the regular oven. Gotta ask though- how do his eggs turn out? MANY years ago, I tried to prepare scrambled eggs in the microwave, and both the texture and taste was like eating a sponge! Kinda looked like it, too.
