see that sounds to me like you're comparing to shitty pre-packaged whole burgers, not just frozen patties.
When using frozen patties the rest of the process is all basically the same as with fresh patties, which is precisely the point. You can just chuck a stack of patties in the freezer and pull them out whenever you want to make some burgers.

just because one thing is frozen doesn't mean everything is lmao, that's a weird strawman. It's not all or nothing, you can freeze just the bits where it works well and provides benefits. Though whole frozen meals are perfectly fine too, because they pick dishes where it actually works. You can totally live off of nothing but frozen meals (the stuff you'd call TV-dinner in the US for some god forsaken reason) and probably have a significantly healthier diet than a lot of people.
