Step 1

Heat vegetable oil in a large cast iron skillet over medium high heat. Add ground beef and cook until browned, about 3-5 minutes, making sure to crumble the beef as it cooks; drain excess fat.

Step 2

Add onion and bell pepper. Cook, stirring occasionally, until tender, about 3-4 minutes.

Step 3

Stir in tomato paste, garlic, paprika, chili powder and cayenne pepper until fragrant, about 1 minute.

Step 4

Stir in beef stock, scraping any browned bits from the bottom of the skillet.

Step 5

Stir in ketchup, Dijon, Worcestershire and brown sugar; season with salt and pepper, to taste. Bring to boil; reduce heat and simmer, stirring occasionally, until thickened and flavors have blended, about 15-20 minutes.

Step 6

Serve immediately.
