Even when I was single I’d cook big batches and intend on having leftovers the next day and something for the freezer. I rarely found packaged meals appealing - usually they were either too bland or too sugary or too salty or all 3. This was some years ago but i’ve not revisited since.
I don’t like the texture of the meats they use in frozen foods/meals. The chicken used is just gross to me. Even the beef used in pot pies. If it’s a hamburger dish then I can sometimes eat it. Yeah, I don’t buy them much.
