It really varies, as there's lots of different kinds of Chinese here (Taiwanese Americans, descendants of Fujianese immigrants from the 19th century, modern expats from the PRC, Yuenan Huaqiao, etc.) but at least in my experience (my father's side of the family, although widespread in a lot of countries and originally from the mainland, has a majority Singaporean/Malaysian background), I usually have lunch with my extended family and get 红包, lol. We eat curry + fish + chicken + noodles etc. With my mother's side of the family, when I go see them in the following days, I typically have a more "countryside" style of meal, lol.
