My diabetes meal was the same on my earlier flight from Hyderabad to Singapore. The breast of chicken was 3-4 oz piece. It was difficult to cut it on the smaller pieces in the tray. Prefer pre-portioned chicken breast cubes. No need to make it a chore. I could manage to handle, but be considerate to seniors who might have limited mobility etc.
