I haven't that too much thought, however, I do have an idea inspired by real world wartime and medieval meals. They are very large but also very egotistical. They won't eat something if they don't like (whether that be texture or flavour, even if eating could save their life). They common place meal for an average Arkiahn civilian is hearty but flavorful, a dish simply refered to as "Kenyanii" as goes as follows(measurements and time translated):
" a slab of slow smoked meat of choice (all though one should prefere a meat of the home world cattle, 1lbs per person) ensure the meat has been treated proper (8 hours minimum) and prepare sauce as directed: 1cup chen, grounded, half teaspoon peltine extract, and 2 cup of crill (some sort animal blood stirred with alcohol). Add together along with optional custom seasoning blend if so desired, and bring to slow simmer adding PURIFIED ONLY water to ensure smooth texture for 1 hour. Prepare a collection of chopped and baked Akinlina for half hour (potato like vegetable, somewhat sweet) add a drizzle of warm crell to marinate while rest of dish is cooked (lesser quality blood found to be extracted from certain slave species). the dish I brought together almost like that of a thick stew, the meat and Akinlina added into the sauce along water if desired to be loosened. The recipe does not specify but it is common for other vegetables to be added to enhance.
The dish is most interesting, blood is common place as a part of diet, and depending on blood, can effect the flavour and colours. The meal is described as Earthy, strong in flavour and could be considered to "stick the ribs". It I also risky, blood carries germs, and while Arkiahn stomachs are tuned to digest copious amounts of it with ease. Not everyone is accustomed to it and can be nauseating. So alternatives can be made with less blood or non at all. This meal recipe.provided.is.super basic and has hundreds if not more variations.
I will admit, your question made me realize I should consider national meal of species in my universe, as most of what I told you kinda came as I typed, subject to change, but it is something I should seriously flesh out! Thanks for that, might even right down actual fictional recipes lol, could make a cookbook for my universe 😂👍
