It depends on where you are designated. One thing is certain: regardless of where you, are the food is terrible. Think lowest bidder won contracts. Expired and waste.
You’ll be fed stuff that’s gross but filling, if you can stomach the taste of it.
A typical breakfast might consist of “biscuits and gravy” which is nothing like actual B&G, it’s more like shortbread squares covered in a tan gravy made from water and powdered gravy mix and some TVP (texturized vegetable protein AKA soy) to simulate sausage, but it has the texture of overcooked hamburger and the flavor of nothing.
