Heat a large casserole dish over medium heat and add the oil, onion, capsicum and garlic. Fry for about 4 minutes, until the onion starts to brown.
Add the beef mince and stir to combine. Add the oregano, rosemary, bay leaves, stock powder, wine and tomatoes and roughly break up the tomatoes using a wooden spoon.
Season very well with salt and pepper and bring to a simmer. Reduce the heat and simmer for 30 minutes (you might need to add water from time to time if the mince looks too dry), then mix through the olives and parsley. Serve with some toasted sourdough drizzled with a little olive oil.
