I don't keep track of the lunar calendar so I don't know which days of the month are Buddhist vegetarian days. But when my oldest uncle's wife (who does observe such things) called and asked if I eat vegetarian because she made some udon, I wasn't gonna turn her down.
So I got this tray of banh canh chay (Vietnamese vegetarian udon), mien chay (Vietnamese vermicelli noodle stir-fry), and che (Vietnamese dessert soup) with mung bean and tapioca. Normally, banh canh is made with crab and/or shrimp, but my aunt used several different kinds of mushrooms. It was quite tasty.
I miss my mom's and grandma's banh canh though. They made their own noodles. My mom's is thicker and doughy, my grandma's were thinner, translucent, and chewy.
And this is the vermicelli stir-fry. Mmm. I do so enjoy living near my relatives.
