Same here! Both my mom and her mom hate cooking. Pre-made meals weren't a thing when I was young and we couldn't afford takeout food so my mom used to cook these hugeee pots of bolognese/stewed meat/chicken curry that were made to last the entire week
There were always fish fingers in the freezer for when the huge pot of food was over and there wasn't another one ready for dinner. I absolutely loved having fish fingers because my mom was (is) such a terrible cook. I had a coworker whose mom was a single mom with 4 kids, and he hated fish fingers for the same reason I loved them: fish fingers was what his mom used to cook when she didn't have time to cook dinner!
My paternal grandma enjoys cooking and is a good cook (with the recipes she knows and that she's been cooking all her life), but neither my dad nor my aunt take after her, both of them hate cooking.
I learned to cook and started enjoying it it when I went to live alone. Such as in your case ot definitely wasn't something passed on from the previous generation.
