1. Preheat oven to 160°C (140°fan-forced). 

2. Heat oil in a large ovenproof casserole dish over medium-high heat. Add beef and cook for 2-3 minutes each side or until browned. 

3. Add orange zest and juice, honey, mustard, stock, tomatoes and oregano. Bring to the boil, cover with lid and place in oven. Cook for 90-100mins or until beef is tender and falling apart. Season to taste.

4. When roasting beef, you can prepare some side dishes. After steaming the prepared potatoes, cut them into pieces with tomatoes for standby. Tender spinach leaves can be boiled quickly, or can be matched with some directly edible vegetables.

5. After the beef is done, put it on a plate with potatoes, tomatoes and vegetables, and sprinkle some oregano leaves for decoration
