Make a new sausage recipe that combines mutton and rabbit.
e.g:
2 mutton + 1 rabbit + onion + intestines = some combination of Per and Agi?
Why?
There are currently not many uses for rabbit nor sheep, and bringing home rabbit from a hunting trip has not seem worth the slot in ages.
In addition my cupboards tend to fill up with mutton, as boar meat tent to go to BBBs.
Catching and selling rabbits could even be an accessible trade goods for complete newbies if the resulting FEP are desireable to large groups of players.
People who can reliably kill mouflons (or somehow got their hands on a herd of sheep) will also have a meat based source of (in my example) Per and Agi, without needing the skills to kill boars or deer.
