I would say polenta (mămăligă in Romanian) is the easiest to prepare - https://www.chefspencil.com/traditional-romanian-polenta-mamaliga/

It’s not a meal by itself, but it’s delicious with telemea cheese (you won’t find any outside of Romania, can probably be substituted by feta cheese best), sour cream and a fried egg on top. Add a smoked sausage and you got a feast :)
