If you’re in Taiwan, make a trip to your local 50% Fifty Percent Píngjià Shíshàng (50% FIFTY PERCENT 平价时尚) (50 percent bargain-price fashion) and pick up one of their shirts of various Taiwanese foods, each of which is labeled in romanized Taiwanese. (Place name hashtags (e.g., #Yilan) are not included on the shirts.)
The only problem is that you may want to carry a magnifying glass with you, because the images and letters are tiny. (C’mon, people! When you want people to read something, size matters.)
This is the one I picked for myself: tshang-iû-piánn (in Mandarin: cōngyóubǐng / 蔥油餅 / 葱油饼). Those scallion pancakes are wonderful.
