its no good for veg again as is, it loses most of its nutrient value within 6 weeks.
i do one of two things with mine (and as a gardener i get loads) i either use it for topping off flower beds or more often i sieve it back into my compost bins to mix with the new stuff, the advantage of this is that its a brown layer to mix with green stuff to make good compost!!!
i dont grow veg at home due to lack of space and as veg seem to have even more illnesses than rosebushes (which are the bane of my life) im not sure whether spent compost can go onto other veg areas...
