So i just got a new job at a restaurant where I work 6 hour shifts. After 4-5 hours I get a 10 min break where I can eat, but I need to eat every 2-3 hours each day otherwise I start dropping weight. I'm in front of managers and customers the entire time so I can't throw handfuls of food in my mouth, but I was thinking i could either eat a protein bar in the bathroom/hallway really quickly or I could bring some kind of shake that I'd be able to drink whenever. Does anyone have any good recipes or ideas on how to make one?
Preferably with enough calories/carbs/protein for it to count as a meal
