The burgers are advertised as gluten free, antibiotic free, no animal by-products and the chickens are served an all vegetarian diet.
Since the chicken burgers are pre-cooked it makes reheating a breeze. Popping them onto a frying pan I brought them up to temperature and served as I would any normal hamburger. Topped with mustard, ketchup and some fresh lettuce and tomato I was good to go. The burgers are substantial that they're satisfying and are firm when you bite into them. I sometimes find with pre-cooked burgers the consistency can be off ... but these are along the lines of frozen hamburg patties where they stay firm in texture.
Flavor wise I wouldn't say they're overly strong. They're mild, taste like a chicken burger but there isn't any real or even strong spinach or cheese flavor that I found. In my eyes it's a way to get a little protein and (a small amount of) vegetable into your diet without really noticing it. They really aren't bad and I found I enjoy them as a convenience meal - for the days where I need something quick, but don't want to spend much time in the kitchen.
