Creating Korean Street Toast is simple if you follow these easy steps:

1. Prep the Vegetables: In a bowl, combine the shredded carrot, shredded zucchini, and chopped green onion. Set aside.
2. Make the Egg Mixture: In another bowl, crack the eggs and whisk them until well blended. Season with salt and pepper.
3. Prepare the Bread: Take the bread slices and spread a thin layer of mayonnaise on one side of each slice.
4. Heat the Pan: Heat a non-stick frying pan over medium heat and add a small amount of butter or oil.
5. Cook the Eggs: Pour the egg mixture into the pan, creating a thin layer. Let it cook for about 1-2 minutes until slightly set.
6. Add Vegetables: Place the prepared vegetable mixture on one half of the egg. Allow it to cook for an additional minute until the egg is fully set.
7. Assemble the Toast: Fold the egg over the vegetables, then place one slice of bread (mayonnaise side down) on top. Gently press down before flipping to toast the other side.
8. Toast Both Sides: Cook until golden brown and crispy, about 2-3 minutes per side. Repeat the process for the remaining slices.
9. Add Sauce: Once out of the pan, drizzle ketchup and soy sauce on top for a savory finish.
10. Serve Warm: Cut in half for easy eating, and serve while warm!
