Golumpki/Golabki (My Polish MIL used to make quite often) Vina Dosh ( I know it's misspelled) - My uncle was Portuguese, and this was my favorite dish of his. A Cuban dish (my cousin is from Cuba) I believe called Ropa Vieja
I would say just about most everything I prepare now is "ethnic" in that it is nothing I grew up with in the 50s and 60s. Brown rice and tempura , sukiyaki, kinpira, nabe, norimaki, sushi, pesto, broccoli rabe, mustard greens, millet, gravlax, chow chow, dolmas, broth bowls, okonamiyoki, tacos, kasha varnishkes, hummus, curry, gobi aloo. etc. About the only things I still eat that I grew up with are potatoes and fried fish and seafood.
