Many years ago there was a health food restaurant on Hollywood's famed Sunset Strip named The Aware Inn. It was the first to make hamburgers, called "Swingers," stuffed with a mix of onions, tomatoes, and green peppers — almost a salsa except it was sandwiched between the meat. They tasted so good, we have been preparing hamburgers this way ever since.

　　

Ingredients

Makes 4 servings

　　1 garlic clove, minced

　　1/4 cup yellow onion, peeled and finely diced

　　1/4 cup tomato, finely diced

　　1/4 cup green pepper, finely diced

　　1 teaspoon dried oregano

　　salt and freshly ground black pepper to taste

　　1 pound lean ground beef

　　1 egg

　　3 tablespoons extra-virgin olive oil

　　2 large yellow onions, peeled and thinly sliced

　　

Step 1

In a medium bowl, combine the garlic, diced onion, tomato, green bell pepper, and oregano. Add the salt and pepper, and mix well. Cover with plastic wrap and set aside.

　　

Step 2

In a large bowl, combine the ground beef, egg, salt, and pepper. Shape into eight 4-inch round, flat patties. Place a spoonful of the vegetable filling in the center of one patty, top with a second patty, press down firmly, and shape into a round, carefully sealing the sides by pinching together. Repeat with the remaining patties.

　　

Step 3

In a large nonstick skillet, heat the oil over medium-high heat and sauté the sliced onions until lightly brown. Transfer to a bowl and keep warm. Transfer to a bowl and keep warm. Brown the hamburgers for about 5 minutes on each side, or until cooked to medium; return the onions to the pan and heat. Serve immediately.
