from looking at choices for the dining plan for kids it seems they only get mac and cheese and chicken nuggets- I would love for the kids to have other choices... am i missing something
Yep, you are missing something

A lot of the kids' CS choices are not very appealing, but some are better if you look for them, more interesting, more variety:
MK -- CS looks pretty lame, even for adults.
Casey's Corner: has no kids' menu, kids have same options as adults.
El Pirata y el Perico: taco, cookie, and beverage
Main St Bakery: doesn't look like there's a kid' menu, so same options as adults.
AK -- CS not great options for kids
Flame Tree: chicken wings or hot dog (may be ok)
Tusker House: mac and cheese or chicken drumstick (may be ok)
Pizzafari: cheese quesadilla may be ok, but really odd there is no pizza for kids!
MGM -- CS options not great for anybody, but...
Catalina Eddie's: don't see kids' menu? same options as adults?
Toy Story Pizza Planet: no kids' menu, same options as adults
ABC Commissary: gets bad reviews, but kids' meals includes fried fish and vegetable noodle stir fry, specifies fries and soda available on request
Epcot -- some really unique and appetizing-sounding CS options for kids:
Cantina: beef burrito and soft drink
Electric Umbrella: standard chick nuggets and mac & cheese, but also turkey and cheese pinwheels, at least it's something different...soda and fries on request
Fountain View: don't see kid's menu -- same choices as adults?
Sommerfest: don't see kid's menu -- same choices as adults?
Sunshine Seasons: sweet and sour chicken, mac & cheese, mini sub, chicken leg
Yorkshire Fish Shop: don't see kid's menu -- same choices as adults?
Lotus Blossom: egg roll and beef fried rice
Tangierine: burger, pizza, or chicken tenders, all with fries and drink
Yakitori: teriyaki chicken w/veggies, rice, and soft drink
DTD
WPE: chicken fingers, mac & cheese (the GOOD stuff), cheese OR pepperoni pizza
EOS: PB&J, grilled cheese, turkey and swiss, pizza sandwich
Food Quest (in Disney Quest, requires admission): pasta, burger, hot dog
Cooke's: fish, battered chicken skewer, baby sausages, all with chips (fries)
TS options are better...and I'd do a lot of buffets with kids, then they can have whatever they want.
