A hearty and flavorful one-pan dish combining tender beef, wholesome barley, and vibrant vegetables.
Heat a large skillet over medium heat and add the ground beef.
Break the beef into small pieces as it cooks for even browning.
Add the chopped onion, celery, and bell pepper to the skillet.
Cook the vegetables until they are softened and fragrant.
Stir in the salt, pepper, marjoram, Worcestershire sauce, and tomato paste.
Mix well to coat the vegetables and beef with the seasonings.
Pour in the diced tomatoes and water, and bring the mixture to a boil.
Stir occasionally to prevent sticking.
Add the quick-cooking barley, reduce the heat to low, cover, and simmer for 35 minutes.
Check occasionally and add more water if the mixture becomes too dry.
Serve the dish warm, garnished with fresh parsley if desired.
Pair with a side salad or crusty bread for a complete meal.
