help with chinese rice rolls

thanks in advance fellow chinese food lovers!

other than minced pork, shrimp, and then long crispy deep fried rice gluten log donut thingy ... is there anything else delicious and acceptable i can put inside? i am buying them premade from asian supermarket.

interested in knowing any suggestions! and what texture-wise can actually fit in there? veggie or meat. i have bad teeth, lol ...

(take in mind, of course i can basically chop of anything and wrap inside, but it wont be steamed directly into the raw dough, than if i had made the dough myself, which i dont how to, lol)

also i cant find a youtube tutorial that can make regular supermarket storebought ground pork - into finely minced pork that has an even more pastier, velvet quality. similar to the dim sum restaurant ones i ate growing up. i also dont have a meat mechanical grinder\hasher.

(basically, i dont want bits of pork to fall out of the rice roll as i am eating it)

do i need to break the down ground pork even more by using the edge of a knife and scraping it into a paste?

the only vidoes i am finding are steamed minced pork on a serving plate, but thats a different dinner table side dish that just meant to be eaten like that - not used as an actual stuffing or spread. and other videos coming up are rice PAPER applications with pork inside, that i am not looking for. those are delicious too! but those are moreso cold dishes, which i am not looking for.

i am looking for the chinese pork cheung fun like at the dim sum!

thanks very kindly! hope you all also have a wonderful summer weekend!
