If I am travelling and want fast food..I'll usually stop at Subway. Most of their subs have a healthier balance, considering the food pyramid.. bread, dairy, meat and a quantity of fresh vegetables. I haven't tried their breakfast food yet..
Hamburgers..I prefer my own, although I may eat others when I travel. Last fall I probably killed the best eating venison I ever shot. I got him in a small woods surrounded by fields of corn, soybeans and alfalfa. Saved just a little steaks & tenderloin..rest into burger.
For beef, I have a friend who raises Scottish Highlander cattle. These tough little fellows live primarily upon roughage and very little grain.. This is the great beef I prefer.
As far as sushi etc... If it walks, runs, swims, flys or crawls.. I want it cooked first..but that's just me.
OH, BTW: ..I do sometimes eat steak..but it must be well done.
If I wanted it as raw as some do, that's almost like biting a cow in the butt!
