There are many delicious ways you can fill bao buns. Some other suggested fillings for bao buns would be to use shredded pulled pork, beef brisket or chicken to fill your bao buns. I love the pulled pork with a cabbage and carrot slaw. A sticky teriyaki sauce would work really well with some crispy skinned chicken thighs, that's another favourite of mine. I also like using vegetables and making a quick tempura batter, fill the buns with a little sriracha mayo, a quick cabbage slaw and then fill with the crispy tempura. The possibilities are endless for ways to fill these bao buns and they're just so convenient you can buy the bao buns ready made.
