Okay, I checked on the carb counts for the ingredients in the Squash Au Gratin.

Fiesta Cheese Soup 9 net carbs/serving size 1/2 cup (before any other ingredients are added)
Squash (cooked) 6.5 net carbs/serving size 1 cup
Durkee Fried Onion Rings w/Cheddar 3 net carbs/2 tbsp.
Sour cream 1 net carb for 2 tbsp.

This makes a big baking dish full so I would imagine if you break it down into the amount of servings you eat, the carb count is pretty good. Portions mean a lot!

Wasn't there a website somewhere that you could figure this out???
