Preheat oven to 160°C (140°fan-forced). 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. Add orange zest and juice, honey, mustard, stock, tomatoes and oregano. Bring to the boil, cover with lid and place in oven. Cook for 1 ½ - 1 ¾ hours or until beef is tender and falling apart. Season to taste.
Serve beef with sauce, potatoes, baby spinach, tomatoes and extra oregano.
Chuck or gravy beef would also work well in this recipe.
Add star anise, a cinnamon quill or dried chilli for extra flavour.
Serve with mash, rice or quinoa for a delicious weeknight dinner.
