It has always been the tradition in my family to observe strict vegetarian dietary rules before noon on the first day of Chinese New Year. Lunch would be served at around 11am and it would always be the same two vegetable dishes accompanied by Cheng Teng (sweet dessert soup).
In addition to the reunion dinner, we would all be looking forward to this special vegetarian lunch. As of today, we still do not know why our mother never recreates all three dishes on any of the 364 days of the year.
Any of the dishes when presented on any other day alone without the other two simply doesn't taste as nice. :)
