They eat the dainty food of famous chefs with the same pleasure with which they devour gross peasant dishes mostly composed of garlic and tomatoes or fisherman's octopus and shrimps fried in heavily scented olive oil on a little deserted beach.
Right now I'd love to be sitting on a Greek island somewhere because of being Greek American eating great octopus salad and some fantastic lamb. Or sipping a little ouzo. I think the Mediterranean diet is one of the healthiest... Lots of nuts vegetables fruits fresh fish lean meats yogurt.
You can't escape the taste of the food you had as a child. In times of stress what do you dream about? Your mother's clam chowder. It's security comfort. It brings you home.
