I looked around and couldn't find a definitive answer either....

"We ordered it for my daughter in April. It was pretty basic- thick bread, no crust, cheddar, cut into sticks."
This is the review from EasyWDW:
"This one is squarely aimed at pleasing most kids’ simple palates. The sandwich is just a thin layer of Kraft-Singles-quality cheese on white bread. The soup has the flavor and consistency of Chef Boyardee Spaghetti O’s without the pasta. I don’t necessarily mean this to sound overwhelmingly negative as this is likely exactly what kids are after, but I don’t think it’s a good substitute for an adult looking for a smaller meal."
