Before starting eating, students should put their hands together and recite the Bhojan mantra with devotion. In my childhood days, we used to chant this mantra before having food. Its my personal experience that this mantra gives energy to students.
This Shanti Mantra is taken from the krishna Yajurveda Taittiriya Upanishad (2.2.2).
AUM saha navavatu, saha nau bhunaktu
Saha veeryam karvaavahai
Tejasvi naa vadhita mastu
maa vid vishaa va hai
AUM shaantih, shaantih, shaantih.
