In a large mixing bowl, combine the beef with olive oil, minced garlic, dried oregano, fresh lemon juice, paprika, salt, and black pepper. Toss everything together until the beef is well-coated. Allow it to marinate for 15 minutes at room temperature.

Heat 2 tablespoons of olive oil in a large skillet over medium heat. Once hot, add the chopped onion and diced bell pepper, stirring frequently. Cook for 5 to 7 minutes, until the vegetables have softened.

Increase the heat to medium-high and carefully add the marinated beef to the skillet. Sear the beef for about 5 to 8 minutes, turning occasionally until browned.

Pour 1 cup of beef broth into the skillet, scraping up any flavorful brown bits. Bring the mixture to a gentle simmer.

Once simmering, reduce the heat to low and cover the skillet. Allow the beef to cook for about 30 minutes, stirring occasionally.

After simmering, taste your Greek Beef and adjust seasoning if necessary with salt, pepper, or lemon juice.

Remove the skillet from heat, garnish with fresh parsley, and serve hot with lemon wedges.
