You can make the usual amount of soup and freeze most of it in single-serving containers. Or you can make the components -- cook the broth, brown the chicken, chop the veggies -- and freeze those in ways that allow you to remove the amount needed to cook yourself a bowlful.
The latter is how I sometimes do the stir-fry thing, minus the freezing part. I chop all the vegs and put them in separate airtight containers, then into the fridge. When it's food time, I fry up the oil and spices and choose bits from the various containers. Depending on the starting freshness of the veggies, I can keep this going for up to five nights in a row. Fresh stir-fry every time!
I should try this with frozen bits one day and see how that works. I imagine it's a tradeoff between longer keepage in the freezer vs. no freezer burn in the fridge.
