Applying for food benefits after losing my job (Tucson)

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. There are 8 people in my household. What did you submit and how long did approval take?

I sent my last two pay stubs, the separation letter and a bank statement. I heard back in about 4 weeks, and my county offered an interview by phone.
