Tuna Burgers with Vidalia Onions and Chipotle Sauce Recipe

Tuna burgers are a most welcome and most delicious change from the more familiar beef burger. And topped with chipotle sauce (included), tuna burgers can reach great gourmet heights. I made these tuna burgers at last Monday’s demo, Fish Cookery, chipotle sauce and all, and trust me, I had a room full of happy campers!

Ingredients

3 tablespoons olive oil
2 large vidalia onions, sliced very thin
2 pounds ground tuna (meat: substitute bison, lean beef or turkey)
Freshly ground pepper to taste
6 hamburger buns, split open (I recommend you experiment with sprouted bread buns: Ezekiel etc....)
2 beefsteak tomatoes, thinly sliced
Chipotle sauce (recipe follows)

Chipotle sauce:

2 canned chipotle peppers, with 2 tablespoons of the liquid
1/2 cup ketchup
4 large cloves garlic
6 sprigs cilantro
Salt to taste

Puree all ingredients in a food processor until smooth. Store in a glass jar in the refrigerator. Makes about 1 cup.

Instructions

Heat the oil in a skillet, and add the onions. Cook, covered, over medium heat, until brown, about 20 minutes. Set aside. Preheat the broiler (or the grill, if you are cooking outdoors). Combine the meat and the ground pepper. Form about 6 patties about 1-inch thick. Broil about 2 minutes on each side for medium-rare.

Put the buns under the broiler, split side up, for about one minute.

To serve, spread some of the onions on each bun, and top with a hamburger, sliced tomatoes and a dab of chipotle sauce (recipe follows).
