Preheat the oven to medium heat.

Place the beef pieces in an oven tray. Sprinkle with cinnamon and mix until all pieces are coated.

Place the tray in the oven and let them cook slightly until they start changing color on all sides. Remove from the oven and set aside. The meat shouldn't be completely cooked.

Heat the vegetable oil in a frying pan and fry the potato pieces until they turn golden. Remove from heat and set aside.

Add all the vegetables, tomato paste and fried potatoes to the cooked beef, season with pepper and salt and bake for 30 min in the oven, on medium heat.

Remove the tray from the oven, add the baby corn then place the tray again in the oven. Let it cook for 5 more minutes.

Serve hot with vermicelli rice or pita bread.
