Sherman's Deli isn't kosher, but, in the past, I have noticed prepared, wrapped, hechshered vegetarian sandwiches at the Palm Springs counter.
I understand the Palm Desert location might have more wrapped kosher items.
Also, there is a Trader Joe's in Cathedral City; Clark's (a health food store-Palm Desert) has a large selection of kosher items. Ralph's and Albertson's both carry frozen kosher entrees.
