Korean Street Toast (Gilgeori-toast 길거리토스트). It’s basically a Korean breakfast sandwich. There’s no one way to make it but it’s usually egg mixed with various veggies that is fried into a patty and put on buttered toast (think made like a grilled cheese). It’s gotten super popular in Korea as a quick street food breakfast and there’s Korean Toast shops popping up all around the world now. Here’s a recipe from Maangchi, but you can put basically anything you want on it. This one had ham, cheese, and a sweet gochujang sauce on it. Got it from a vendor in a local Korean themed food hall.
After seeing your post I’ve made this for breakfast twice, thanks for the suggestion!
It’s wild how the sugar works here, I’m honestly surprised as I found the idea of putting granulated sugar in a sandwich off putting but it really does make the vegetables shine. It’s a quick and easy recipe, too, I’m absolutely putting this in the rotation for morning meals.
