Chinese-Style Beef Curry Bun

What should I do with the left over roasoted beef?

here is another idea...

This has been my 4th or 5th time that I work with yeast....I'm getting better at it. Today, the yeast rise very well since I put it a warm oven. Before, it was too cold inside the house, so it didn't rise properly.

Just need more practice and it will get even better. lol.
