Our Big Kitchen, abbreviated as OBK, is a charity based in Sydney, Australia that provides a large commercial grade kitchen for community use. The kitchen facilities are used by various community groups to prepare and distribute meals. The community kitchen concept is similar to that of a soup kitchen, but incorporates volunteer and common-effort aspects closer to that of a community garden. Housed in the Yeshivah Centre, Sydney, Our Big Kitchen, a project of the Sydney Jewish community, is accessed by a large spectrum of both Jewish and non-Jewish community groups. OBK was founded by Rabbi Dovid Slavin and Laya Slavin in February 2005.
