Money Diet, week 19: The serving size trap

I'm thinking a lot about serving sizes this week. Several days ago, I went to the grocery store and bought a low-fat garden vegetable lasagna frozen meal. Made by a company called Cedarlane, it was very tasty and pretty healthy (I have no beef with the food and am not really looking to pick a fight). But while I was in the store, I glanced at the "nutrition facts" on the back of the package and saw that the total fat was three grams, the sodium count was 390 milligrams and the calories were only 180.

That seemed pretty good to me, so I bought it.

When I got home and popped the lasagna in the microwave, I looked a little more closely at the package. That's when I noticed, right above all that other information, it said "Servings per container: 2."
