Inside Out Burgers with Cheese

Inside Out Burgers with Cheese
From: The 30-Minute Kosher Cook by Judy Zeidler; William Morrow & Co.
Makes: 4 servings

1 garlic clove, minced
1/4 cup yellow onion, peeled and finely diced
1/4 cup tomato, finely diced (or mushrooms)
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
cheddar or American cheese, shredded; slices for top

In a medium bowl, combine the garlic, diced onion, tomato, green bell pepper, and oregano. Add the salt and pepper, and mix well. Saute all veggies except the sliced onions till veggies are limp. Cool and Cover with plastic wrap and set aside.

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 shredded cheddar or American cheese, then 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.

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. . Brown the hamburgers for about 5 minutes on each side, or until cooked to medium; you may top with a slice of cheddar or American cheese. Return the onions to the pan and heat. Serve immediately. I serve this alongside a salad…very filling.
