Basically, my experience is that there is one good brand of anything.
Morningstar Farms: Chicken Nuggets, black bean burgers, Buffalo wings, corn dogs, bacon, breakfast sausage
Field Roast: Other sausages (frankfurters, italian, apple sage or spicy Mexican chipotle - sweet zombie Jesus those things are good)
Tofurkey: Roast and sliced turkey
Trust me - I've been through a lot of really lousy substitutes to get to these.
