I would look to see what planting schedules for your area say. You will probably have to provide shade during the height of the day for any sprouting plants.
If, however, you are a couple of weeks to a month or so before fall planting, you could plant exclusively soil-building plants, and then chop them for mulch when you seed in late summer.
I don't know how fall is where you are, but in Toronto where I am, zone 6a, we plant crops in late August that will be harvested around first frost in late October/November.
These are usually greens, or plants that will develop
root systems and go dormant in the winter to produce an early spring crop.
Let us know, and good luck.
