Not Okonomiyaki: buchujeon or pajeon

Okonomiyaki, the Japanese pizza—a pancake served “as you like it” with your favorite toppings—is delicious; I’m inspired to try as many kinds as I can. Koreans enjoy a similar pancake dish called jeon; the most basic version is made with only scallions and is called pajeon, or p’ajon, pajon, pa jun, pageon, or (oddly) buchimgae or buchujeon. The last two may refer to pancakes which use garlic chives (or Chinese chives) rather than green onions; I don’t know. buchimgalu=packaged mix?
