How to Make the Onion Egg Sandwich
Step 1: Prep the Egg Mixture
Crack all the eggs into a bowl, add salt and black pepper, and beat them well with a fork. Stir in the chopped tomato, blue onion, and green onion. Mix everything until well combined.
Step 2: Cook the Eggs
Heat 1 tbsp of vegetable oil in a pan over medium heat. Pour in the egg mixture and scramble gently. Stir occasionally until the eggs are cooked but still moist and fluffy. Set aside.
Step 3: Toast the Bread
Spread a little butter on each bread slice. Toast the slices in a pan or sandwich press until golden and crispy. If you're in a rush, even a quick toast in the toaster will do the trick!
Step 4: Assemble the Sandwich
Spoon a generous portion of the onion egg scramble onto one slice of bread, top it with another slice, and press gently. Cut into halves or quarters, and you’re ready to eat!
Tips & Twists
- Add cheese: A slice of cheddar or mozzarella makes it melty and rich.
- Extra crunch: Add fresh lettuce or cucumber slices.
- Spice it up: Add a pinch of chilli flakes or a dash of hot sauce to the eggs.
- Make it sweet-savoury: Add a drizzle of ketchup or sweet chilli sauce before closing the sandwich.
