>56oz according to google which lists beef at 7g/ounce and mushrooms at 0.9/ounce

Edit: legumes are more practical, green peas give you 2g/oz and peanuts can be 7g/oz shelled according to google, (though they are different proteins than the beef). Mushrooms are good for texture and some like shitaki can give the umami taste, but they aren’t a nutritional meat substitute on their own.
