My mom was pretty accommodating at dinner time - if she made something that one of us didn't like, she said we at least had to give it a try and if we still didn't like it, there was always bread (or rolls) and butter on the table and we were welcome to subside on that. She didn't really force us to eat anything.
There were 5 kids, plus mom and dad and usually grandma so if she was making something that just a few of us liked, she'd say you don't have to eat the stuffed cabbage, or liver, or SOS, etc. and would let us fix ourselves a bowl of cereal. In our house, I considered city chicken or SteakUms a treat because I was usually the only one who liked those things so on those days I'd be the one digging in while my sisters or brothers might opt for the cereal.
FWIW, as an adult, we still occasionally buy SteakUms (and by occasionally, I mean maybe once a year). They work pretty good to make sandwiches and my daughter actually enjoys them. I also once saw a show or read somewhere about how they are made and feel much less grossed out by them now. IIRC, it's good quality roast beef but the developer happened to invent some sort of process for slicing it extra thin AND flash freezing.
