Did you know: it takes about 26 months for a bison to reach maturity. The buffalo grown for Trader Joe's Buffalo Burgers are on large, open prairie ranches and given a choice of whole grains and free range grazing on prairie grass. You see, buffalo, unlike cattle, will naturally select what they wish to eat and they never consume more than their bodies require. Since buffalo meat is lean, it tends to cook faster than beef. However, it's very versatile and easy to prepare. Like these Buffalo Burgers– just defrost and pan-fry or grill, about 5 minutes per side, or until internal temperature is 160˚F.
