In a large pot, cook the ground beef over medium heat until browned and crumbled. Drain any excess fat.
Add the onion, garlic, and bell pepper to the pot and cook until softened, about 5 minutes.
Add the diced tomatoes, tomato sauce, Worcestershire sauce, soy sauce, oregano, salt, and pepper to the pot. Stir to combine.
Add the water and bring the mixture to a boil.
Reduce the heat and simmer for 20-25 minutes, or until the sauce has thickened and the flavors have melded together.
While the sauce is simmering, cook the elbow macaroni according to the package instructions. Drain and set aside.
Add the cooked macaroni to the pot and stir to combine.
Serve the Goulash hot, topped with shredded cheddar cheese.
