I'm making them again for the third time. I owe you a review. These are absolutely the way to go for that burger craving. The Cabernet (or Merlot, or Shiraz) onions make this dish! Sorry, did not have any escarole, but the romaine worked as well. The escarole would definitely give it more flavor (like it didn't have enough). This is truly a keeper recipe and I'll be using it again and again.
DH and I made these burgers last night for dinner and loved them! Like the other reviewers, we really enjoyed the cabernet onions. The only modification that we made was to grill the burgers. This worked really well, and especially, in summer is a great way to avoid heating up the house. The escarole, dijon, and cabernet onions were very complimentary. I will definitely make these burgers again!
Delicious!!! I love bison and its gourmet flavor is enhanced by these wonderful Cabernet onions!! I actually used a Shiraz and its peppery accent really went well with the onions and the burger. I made mini-bison burgers out of some homemade Whole Wheat Rolls that I had baked recently. I used red lettuce instead of escarole because I don't like the bitter taste of escarole or endive. Also, threw in a few fresh shiitake mushrooms with the onions and they were great with the mix!! You could taste hints of thyme in the burger which I just loved!!! Loved this recipe, thanks for posting!!!
These are absolutely delicious. My son and I try to have one buffalo meal a week. This one is going to be repeated again very soon. The onions are also delicious!
