16 oz is a cup, however I wouldn't say thats the best way to measure chicken. Very odd indeed. Must be ground chicken but who grinds chicken much less puts it in a cup??
I finally found all the right measurements for the meats though after some thorough searching, there were many choices to measure it by the oz w/or w/o bones/fat.
Figured out after getting all the stuff out of the fridge and measuring all the info (even vitamins) for the meals I make that my ham and cheese sandwich is only 395 cals 25g protein, my hamburger which is a quarter pounder with double cheese on a potato bun with parmasano and ragu is only 637 cals and 48g protein and 37g fat. Which is amazing since a Big mac is smaller and 750 cals and 45g fat with only 25g protein.
Cook for yourself, you'll save money, eat better tasting food and it's healthier.
