In a large skillet over medium heat, add the ground beef and cook until browned, about 5-7 minutes. Drain excess fat.

Add the diced onion, bell pepper, and minced garlic to the skillet. Sauté for 3-4 minutes until the vegetables are tender.

Stir in the sliced mushrooms and cook for an additional 5 minutes until they are soft.

Season the mixture with salt, black pepper, oregano, and paprika.

Pour in the beef broth and soy sauce, stirring to combine. Let simmer for 10 minutes to allow flavors to meld.
