Always keep cans of chicken broth on your shelves. They last for years, and then can turn any leftover squash you have into a tasty soup, for pennies!
I know a can of chicken broth (1 cup) says it is "2 servings" - they mean that if you have soup with a sandwich, you have a 1/2 cup of soup usually to go as a side dish. However, most people I know would eat the whole can of soup as a main meal, so I'll count one can of soup as a serving for this recipe. If you really do have this on the side along with a salad or sandwich or something, you can cut the carbs in half!
The whole can of soup has 1g of carbs in it, with zero fat, zero cholesterol and zero protein. It also has zero nutrients :) On the up side, it does have a lot of water! So you are staying hydrated by having soup. Still, since it is a zero nutrient food, please don't try to "live" on soup. Low carb is about eating nutritious food all day, not about trying to live on nutrient-less food.
So, on to the squash. I recently made some Low Carb Acorn Squash. This was delicious! When we were done, we had two scooped out bowls, i.e. the "shells" of the two halves of the acorn squash. We had scraped them pretty clean, but there were still of course bits of squash stuck in there. So I put both halves into a tupperware container and put them into the fridge.
The next day, I got a microwave safe bowl and put in the can of chicken broth. I use low sodium chicken broth which is "only " 570mg for a can. That's a quarter of your daily sodium! Still, I tend to eat dishes with no salt at all so for me this isn't bad in the grand scheme of things. This might be the only real salt I take in all day.
Mash the squash shells down into the bowl, so they are immersed. Sprinkle on some cinnamon. Cinnamon is *really* healthy for you and helps you lose weight. Also add in some freshly ground pepper. If you don't have a pepper mill, go out and get one! It tastes SO much fresher than pre-ground pepper does.
Now nuke in the microwave for about 2 minutes. Shake off the shells and toss them. You've got yourself an easy, delicious chicken-and-squash soup that is super low carb and very tasty! It's only about 1g for the entire can. I can't imagine the tiny squash bits really add any real carbs to this dish. They do add flavor, though!
