Lizard meat would be pretty easy to chain if you could hand it in. Tons of wandering lizardmen in the Feerrott and lots of merchants have extra lizard meat on them from newbies. Might be doable with wolf form or elemental illusion from ball of golem clay. Or you could kill dwarven guards to raise Craknek Warriors faction so you can hand in the Lizard Meat, and then grind dwarf faction back up afterwards:
