Kingdom Come: Deliverance 2 offers numerous side quests that Henry can discover while exploring. When you begin the main quest "Into the Underworld," you'll likely trigger the side quest "Feast for the Poor" simultaneously.
How To Complete Feast for the Poor in Kingdom Come Deliverance 2
Speak with Chenyek
You'll encounter Chenyek when starting "Into the Underworld." After inquiring about Goatskin, he'll demand you fight Goliath before sharing information. Once you defeat Goliath, speak with Chenyek again and express interest in joining his group by selecting "I'll drink to it" to initiate "Feast for the Poor."
Steal Sigismund's Sausages

Your objective involves stealing Sigismund's sausages - a relatively simple task. The marked location contains an open barn on the northwest side where you'll find the sausages in a locked chest inside a green tent. Use lockpicks to open it and retrieve the sausages.
After obtaining them, deliver one to Beggar Damian near a tavern in Kutternberg City's southeastern district. Then report to Knuckles, located nearby, who expresses skepticism about Chenyek's plans and offers an alternative path.

Choosing Your Path
You must decide whether to continue helping Chenyek by distributing sausages to beggars around town (identifiable by their kneeling poses) or assist Knuckles by stealing wine from the same camp. The wine is in a central, straw-covered chest with a very difficult lock - requiring advanced lockpicking skills.
Return to your chosen ally to complete "Feast for the Poor," after which you can pursue other side quests like "In Vino Veritas" or resume main story progression.
Kingdom Come: Deliverance 2 is currently available on PlayStation, Xbox, and PC platforms.
