The greens would be done at this stage.
Mix the cornstarch slurry once and add it.
Mix everything and let it cook for a minute.
The mixture will thicken.
Adjust the consistency as desired. If you need thick, add more cornstarch mixture. (The mixture will be thick after some time, so keep that in mind.)
If you need it like soup add hot boiling water. Add cornstarch slurry at the end if you are making soup.
