Heat oil in a large saucepan on medium/high heat and cook the onions, garlic and capsicum for 4-5 minutes or until tender.
Add beef and cook, stirring occasionally until browned, breaking up any large chunks with a wooden spoon.
Add the tomatoes, tomato paste, spices, stock, and worcestershire sauce and stir until well combined. Season to taste with salt and pepper, bring to a gentle simmer and cover with a lid. Cook, stirring occasionally, for 30-45 minutes.
Meanwhile, preheat the oven to 180°C. Rub each tortilla with oil and season both sides with salt and pepper. Cut each tortilla into 16 pieces and cook for 5-10 minutes or until golden. Serve Chilli Con Carne with rice, chips and fresh spring onions.
