Wolfgang Puck Express
is a great option. Either location, though the one in Marketplace has more choices and more seating. The food there is very good. Other than the fact that you order it at a counter and fill your own drinks, it's like sit-down restaurant. We ate there 3 times last trip. So good!
Here's one of our pizzas from WPE-totally shareable.
And here was my favorite-meatloaf
Cosmic Ray's chicken and ribs combo is a great choice. We've had that meal several times and shared it 2 ways (once even 3 ways with my DD, then about 7). The combo is only served for dinner now, after 4 (also just the ribs alone). You can get the same meal for lunch though at Fairfax Fare in DHS.
Also in MK the Fried Shrimp at CHH was a huge serving, and very good. One day we got 3 of them for the 3 of us and we should have just gotten 2 to share. We had tons of food leftover.

Here's 2 of our shrimps and 3 of our desserts.
We also enjoy Cookes of Dublin. Especially the scallops.
Many food courts offer build your own options.

This is a salad from POFQ. Also shown is their 1/2 chicken dinner. Another great value.
Here's a build your own pasta from AoA
Build your own taco salad from Pecos Bills-very sharable with the toppings bar
And here's one meal from Kringla-large sandwich, side, dessert, and drink
That's just some of the larger serving meals you can get that are good.
