There are several methods one could use to recover Ag from AgNO3, the first would be to do as Adam has already done and precipitate AgCl from your solution with non iodized salt or HCl. Then you could fire it with 2:1 soda ash and borax flux to reduce it elemental Ag.
Or you could take it through the refining process with and convert the AgCl to Ag2O with NaOH and reduce it to Ag with sugar. I won't walk through the entire process because this method could be very dangerous to those who do not have a basic understanding of the chemistry involved. The reaction is very exothermic, and proper safety should practiced at all times, a little bit of silver isn't worth a trip To the hospital.
But if necessary I Can detail the process if someone would like to know more!
