That is some wild bias to think this culture wouldn't have cheese; humans have had cheese longer than we can find written language.
Native/First Nation people and Europeans both had cheese for literally thousands of years; beer, bread, cheese, and cooked meat from domestic animals all pre-date writing.
For any fantasy culture to lack such basics is ridiculous; means that they probably haven't figured out much beyond stone tools, not that they have amazing steel and mithril that they invented themselves.
Crazy wild bias to think that they wouldn't have a basic foodstuff.
