Heat the oil in a large pot over medium-high heat. Cook the beef mince in the hot oil until completely browned, 5 to 7 minutes.
Add the onion, garlic, jalapeno chilli, green capsicum, red capsicum, carrots, broccoli, apple cider vinegar, sugar, Worcestershire sauce, soy sauce, salt and pepper to the pot. Reduce heat to medium-low; simmer, stirring occasionally, until the vegetables are just losing their crispness, about 20 minutes. Stir in green beans about 5 minutes before serving.
