I find the premade mixes from Birdseye (sold basically everywhere that has frozen food) to be a pretty good lazy way to get a big meal. Usually a decent mix of meat, veggies, and grain, but the whole bag (3 servings) is only like 600-900 kcal. Sometimes it feels like an obscene amount of food for the calorie count.
Not bad for what’s basically a microwave dinner.
This is the real reason they disappeared - awnings cost money and don’t increase square footage. That’s also why every modern building is a boring box.
We didn’t forget about them, it’s still covered in architecture school. You can even make them look really cool. But they cost money, and that’s a hard barrier to cross.
