*2.2. Sampling Design*

Purposive judgmental sampling was used to select eight out of the 47 counties, and 50 out of over 3000 high schools in Kenya were selected toparticipate in the study. This was done based on preliminary knowledge of the various counties and the number of schools they had in each of the Ministry of Education school categories. One catering manager/head cook from each of the 50 schools was interviewed.
