I've mostly seen these cured sausages grilled or fried and served as a side or main in MN and WI. Accompaniment can include regular or sticky rice and raw vegetables and chili pastes.
The uncured sour / fermented / fresh pork products including sour sausage and sour ham seem to be more commonly incorporated into comfort dishes like fried rice with ginger and egg, fried rice balls (

Breaking the sausage up, saucing, and serving with a runny fried egg a la some Thai and Mexican dishes also feels right to me.
I note that the Hmongtown Market (
