Dominican Chimichurri Burger (Katleti) - cooking recipe

Ingredients

1 pound lean ground beef
1/2 large green bell pepper, finely chopped
1/2 onion, finely chopped
1 tablespoon Worcestershire sauce
1 tablespoon soy sauce
1 tablespoon yellow mustard
3 cloves garlic, minced, or more to taste
1 teaspoon dried oregano
1 teaspoon salt
1 teaspoon ground black pepper
2 tablespoons vegetable oil
4 slices Cheddar cheese (optional)
1/2 cup ketchup
1/2 cup mayonnaise
4 oval-shaped Portuguese rolls, split
1/2 head cabbage, finely sliced
2 tomatoes, sliced
1/2 onion, thinly sliced

Preparation

Mix ground beef, green bell pepper, finely chopped onion, Worcestershire sauce, soy sauce, yellow mustard, garlic, oregano, salt, and pepper together in a large bowl. Form mixture into 4 patties that will fit inside the rolls.
Heat vegetable oil in a large skillet over medium-high heat. Cook patties until browned on the bottom, about 6 minutes. Reduce heat to medium-low and flip; cook for 4 minutes. Top each patty with a slice of Cheddar cheese; cook until cheese starts to melt, about 2 minutes. An instant-read thermometer inserted into the center of each patty should read 150 degrees F (66 degrees C) for medium-well.
Mix ketchup and mayonnaise together in a small bowl. Spread evenly over both sides of each bun. Transfer a patty to each bun; top with sliced cabbage, tomatoes, and onion.
