This Boxed Meal Claims One Cup is a Serving

This meal is only 12 oz., and it's supposedly "about 2 servings".
Stouffer's claims that a serving size is 1 cup. How many adults are full
after eating only 1 cup of food? 

The front of the box brags about its 21 g of protein, but that's for the 

entire package, not the 1 cup serving! Mysteriously though, on the front

where they mention the sodium, it's 470 mg for the 1 cup serving. The

whole meal contains 1010 mg of sodium. That's a big difference!

I skimmed the ingredients before I bought the meal, but I didn't realize it

also contains carrageenan! I try my best to avoid carrageenan.

The packaging is misleading. The meal contains carrageenan, and a lot

of sodium, but it was tasty.
