SNAP after a layoff: what documents did you send? after 17 years as an accounts payable clerk

I got a notice asking for proof of income and I am unsure what to send. I have been trying to stay organised about it. The caseworker asked for bank statements too. Is there an expedited option for people with very little income?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
