everything's stew. everything's a variation of the 4 easiest ingredients for humans to cultivate plus one or two local or regional specials
garlic/onions: aliums that thrive in most climates
rice: grass that can be drowned (to fuck off pests)
eggs: per day, one chicken produces enough binding enzymes to thicken and modify a meal for 5-8 people
veg/seed oils: cooking, flavor, etc
and since that's in the caspian sea area, they also have a ready supply of tomatoes and eggplant from centuries of trading with asia
stew is also - the most forgiving dish regarding meats.. bad cut? Just stew it more.. this can go so far- that soldiers who where starving where used to cooking down the leather of boots and tournisters..
Tomatoes are a New World crop, so those come from the Colombian exchange rather than some sort of thousands-year-old Silk Road trading history.
