## 5 Conclusions and Recommendations
#### Limitation of the Study  
The important limitation of this study was the different method of filling surveys by all study groups (Figure 1). In fact, the highest mean scores were obtained by the study group 2 (teachers and other primary schools' employees) followed by study group 3 (parents). Both groups filled the surveys on site or at home. The lowest score was obtained by group 1 (Social Care Home Employees--22.9), who were answering the questions during StratKIT workshops under the supervision of the workshop leader. We believe that the results obtained from Study Group 1 are the most reliable. An additional limitation of our study is the relatively small sample size of each category of respondents. The larger groups could have shown more statistically significant correlations and a diverse level of awareness and knowledge of environmental, agricultural and health problems. It also important to proceed with caution while interpreting the obtained results as quantification of such a character often requires strong simplification and assumptions, and as a result, important factors may be ignored. **Supplementary Materials:** The following supporting information can be downloaded at: [[https://www.mdpi.com/article/10.3390/su15043620/s1](https://www.mdpi.com/article/10.3390/su15043620/s1)]([https://www.mdpi.com/article/10.3390/su15043620/s1](https://www.mdpi.com/article/10.3390/su15043620/s1)), Table S1: Respondents' opinion on important changes to be made to the menu (questionnaire open question); Table S2: Most popular dishes in the menu among respondents (questionnaire open question); Table S3: Respondents' opinion on dishes considered to be the healthiest (questionnaire open question); Table S4: Respondents' opinion on dishes considered to be most environmentally friendly (questionnaire open question). **Author Contributions:** Conceptualization, R.K., R.G.-W. and E.R. ; Data curation, R.K. and R.G.-W.; Formal analysis, R.G.-W., R.K., K.K., D.S.-T. and H.D. ; Funding acquisition, R.K., R.G.-W. and E.R. ; Investigation, R.K., R.G.-W. and D.S.-T.; Methodology, R.K. and R.G.-W.; Supervision, R.K.; Visualization, R.G.-W., R.K., K.K., H.D. and D.S.-T.; Writing--original draft, R.G.-W.; Writing--review and editing, R.K., E.R., D.S.-T., K.K. and H.D.
