Frozen dinners? You're speaking my language. I'm serially lazy when it comes to cooking, and I've built up a mental list over the years of what's good and bad.
Pizza: Freschetta, hands down. It beats DiGiorno easily, though the latter is acceptable. The generic Walmart DiGiorno knock-off is about the same quality. Tombstone is alright, but I prefer the cheaper Jack's, even though it's smaller. Red Baron is good, particularly their breakfast pizzas (which have egg, bacon, cheese, and white gravy) that I recently discovered. The cheap Tony's crap is to be avoided. As for pizza rolls, Totino's are good, but I actually prefer the cheaper Kroger generic version.
Burritos: El Monterey is the best I've had, whether the smaller ones or the huge "XXL" kind. The "beef & bean" and "bean & cheese" are my favorites. The "Psst..." brand is awful, which is odd since Psst... is Kroger, and Kroger is usually one of the better generic food brands.
Misc TV dinners: Hungry Man is my gold standard. It's still cheap TV dinner food and no substitute for something that's good and homemade, but it's a cut above the typical crap. I've also lately been trying the Boston Market stuff, and found it to be about on the same level. ($2.50 at my local Walmart. Not bad at all. Some chicken nuggets and french fries at the nearby McDonald's costs me $7.) Stouffer's is generally good but I had to stop buying them because they kept disagreeing strongly with my stomach. (Too much grease, maybe? I dunno.) Banquet is cheap as hell but better than you'd expect based on the price. Marie Callender is one of the higher-up brands and they're good, but they ruined pot pies for me by putting big chunks of celery in them. One brand to avoid is On-Cor, which I found comparable to jail food, which is no compliment at all.
Other: You've got Hot Pockets, which Jim Gaffigan calls Diarrhea Pockets for good reason. Some of them can be acceptable, but not much more. They're generally just a big lump of grease; leave it to Hot Pockets to make pizza seem gross. Corn dogs: take your pick. Pretty much any brand will be the same: decent but nothing special. (They're corn dogs, not gourmet dinners.) As for Asian food, I'm limited here in experience since I'm so picky with this type of food, but the Tai Pei stuff has good rice and vegetables but the chicken is lame. I always douse them with Kikkoman soy sauce to compensate.
By the way, there's this website called Freezer Burns that reviews this kind of food. Worth checking out.
Oh, and always cook in the oven. The microwave usually ruins TV dinners.
