This delicious soup is unbelievably hearty. Though it only has 250 calories per serving (1 frozen sealed bag), you may want to split it. I usually serve it with French or Italian bread, and it makes a filling meal. It is close to what you’d receive in a restaurant. Don’t even think about salting it–it’s one of the saltiest things I’ve ever eaten (870 mg of sodium).
There are two methods to cook it, but, trust me, do not microwave it. The best way is to cook it in an oven for at least 40 minutes (400 degrees). I usually cook it 48 minutes and then broil it for the last two minutes because I like the cheese bubbly, golden, and baked on the sides of the ramekin. Be careful–when it comes out of the oven, it is hotter than Hades.
I’ve bought the soup at Costco during late fall/early winter. According to the website, it’s technically sold at Costco from November through March.
