At Magic Kingdom we like both Pecos Bills and Columbia Harbour House. If you want a sit down meal, try Plaza Restaurant. The sandwiches are huge and you could easily share and each get a drink for around $10 per person, possibly even including tip.
At Epcot, I would suggest Cantina de San Angel, Liberty Inn (for usual American fast food), Yakitori House at Japan.
At Disney MGM, go to the ABC Commissary or the Backlot Express
Animal Kingdom has the best of all the counter service restaurants, with Tusker House and Flametree BBQ.
I am looking at my 2000 Passporter Guide to Disney and even then, most of the counter services were averaging about $12 per person.
Also, I know when our extended family goes, we don't spend every waking hour with each other (we would KILL each other

). Why don't you have youre DH suggest that you all separate and meet up at appointed times so everyone gets to see exactly what they want and won't have to wait while others do things they may not want to do?

That way you and your DH can sneak off get some of those sit down meals that you like.
