Even the dinner series of stories needs a solid narrative drive without too much meandering.
Can you lay in a three act structure with entrée, mains and desserts? Is that too boring, too expected, to the same? How can you express more through the dialogue and less via action? What symbols can you fool around with?
What can you serve up differently each time?
What can you hook with?
The screen of your mind
So how do you build in the whole structure and meaning of a feature into a short story?
All the component parts? All the reveals and turns and drops and spins and emotions of a one hundred and ten page screenplay into a radically shorter form? How to write a cutaway? How to write a color grade? A stereo sound effect? A sweep of strings?
How do you generate the emotions generated by a film in the screen of your mind?
