I have many workers on my construction job site that are Mexican and usually someone will bring a beat up old microwave and someone else brings an ice chest full of tacos that their wife made. They are on a soft tortilla and filled with beef or chicken and typically are delicious, and they will either drink a Coke in the old greenish glass Mexican pop bottle or a can of Mexican fruit juice. Their home made tamales are excellent also, but I don't know how they are able to eat the same thing every day.
