Wild Idea Buffalo. Their site has good nutritional information and an interesting review of the the history of Bison.
Buffalo can be a bit dry as it is so lean. Adding in a source of fat, preferably healthy fat like olive oil, avocado etc, will ensure good tasty, moist burgers. I just pulled out what I had in the fridge-some scallion, avocado and blue cheese-and whipped up some quick, mid-week burgers.
Buffalo Burgers with Blue Cheese, Avocado and Scallions; makes four 4 oz patties
Approximately 257 cal, 0.75 grams carbs, 15.5 grams fat, 27 grams protein per patty
1 lb ground Buffalo 10% fat or less
2 oz blue cheese (I used gorgonzola dolce)
1 ½ TBSP very ripe avocado
½ cup finely chopped scallion (light green and white parts)
Enjoy! You can substitute goat cheese or feta cheese; or mix in a TBSP of olive oil and then top with cheddar or Swiss.
