Not sure if cheap.

I use chicken thigh plus chicken stock. I boil chicken in chicken stock. Then get chicken out when cooked and re-add bones to concentrate stock. Do an infusion but with star anise and a hint of chilli. Vegetables use mushroom, carrot and bok choy. Whatever noodles you like.

It becomes more expensive when you add dumplings. I found these frozen polish dumplings ( but not anymore )

Can be filling. Like when Bruce Lee visit USA and bought soups at the airport.
