Method
Step 1
Beat eggs with the cup of milk and a pinch of salt. Whisk until smooth.
Step 2
Strain mixture through a sieve to remove chalazae.
Step 3
Add grated carrot, onion, spring onions, mushrooms, salt, and pepper to the egg mixture. Stir well.
Step 4
Heat a 10-inch non-stick frying pan with 1 tbsp oil over low heat.
Step 5
Pour half the egg mixture into the pan and cook until half-set, about 2 to 3 minutes.
Step 6
Roll the omelet halfway to the middle, applying more oil if needed.
Step 7
Pour ¼ of the remaining mixture onto the empty side of the pan, merging with the half-rolled omelet. Cook until half-set.
Step 8
Repeat with the remaining mixture, rolling fully to form a log.
Step 9
Transfer to a board, cool slightly, and slice into rolls. Serve warm.
