You get proper sized ones from indian food stalls, not the titchy things that supermarkets have.
When I was a teacher ina Secondary school we had an Indian pupil who was more than a bit of a pain
his parents were working with the management and teachers to get him sorted out and make sure he didn;t go off the rails
In the end he got reasonable GCSEs and was headed for college
a few weeks before the end of term his Mum asked if it "would be OK" if she brought in food for all the staff one lunchtime
proper Indian type food
The Deputy Head - who was a "large" man - agreed with enthusiasm
That lunchtime was amazing - the food, including samosas - was incredible
The pupil in question was made to help serve - and kept in line by his elder brother who was back from university. He did seem to enjoy himself!
