Heat olive oil in a large skillet over medium heat. Add diced onion and sauté until soft, about 3-4 minutes. Add minced garlic and cook for another minute.

Add ground beef and cook until browned, breaking it apart with a spoon. Drain any excess fat.

Stir in diced carrots and celery. Cook for 5 minutes, then add frozen peas.

Mix in tomato paste, Worcestershire sauce, and beef stock. Stir well and bring to a simmer.

Simmer for 10-15 minutes, allowing flavors to meld. For a thicker consistency, stir in a cornstarch slurry.

Season with salt and black pepper to taste. Serve hot with your favorite sides.
