Season ending , cleaning up broccoli, lettuce beet tops, weeds & other garden plants that needed pruned but no browns to add.
What to do??
I have tons of Horse Manure compost.
So I added 3 wheel barrow loads of done 2 year old, HM compost & mixed it in.
Should work. eh?
Also added a load of soil I pulled out of the Green house this spring so I could add new compost to the soil boxes, a perlite mix.
I mean it is brown.
5' X 5' X4' bin of 2 yr old HM compost.

Garden compost bin 6' wide, 5' deep, 5+ feet high. 2' of garden plants, mostly broccoli leaves. Mixing in HM compost.
