Place the round steak on a cutting board. Use a meat tenderizer to pound it well. Make it thinner and softer. This step helps the meat cook evenly and become very tender.

In a bowl, mix flour, salt, pepper and paprika. Coat each piece of steak in the flour mixture. Press lightly so the flour sticks well on both sides of the meat.

Heat vegetable oil in a large skillet over medium heat. Add the steak pieces carefully. Brown them for about 3 minutes on each side. Remove them and set aside.

In the same skillet, add sliced onion and bell pepper. Cook for about 5 minutes until soft. Add minced garlic and cook for one more minute until fragrant.

Pour in diced tomatoes with juice and beef broth. Add Worcestershire sauce and dried thyme. Stir everything well. Let the mixture simmer for 3 to 4 minutes.

Place the browned steak back into the skillet. Spoon some sauce over the meat. Cover the skillet with a lid. Lower the heat and simmer for 1 hour.

After one hour, check the meat with a fork. It should be very tender. If needed, cook for another 15 to 20 minutes until soft and juicy.

Turn off the heat. Let the dish rest for 5 minutes. Serve hot with mashed potatoes, rice or buttered noodles.
