Author and illustrator Jane Breskin Zalben has a picture book "series" (meaning recurring characters, ie Rosie, Beni) with Jewish themes; titles off the top of my head and memory include HAPPY PASSOVER, ROSIE, HAPPY NEW YEAR, BENI, etc.
Hold on... Okay. Just checked Amazon and those two are published by Henry Holt. And there are more in the Zalben series so you may want to add these to your reading list.
