Step 1
Put the eggs into a small saucepan of cold water, place over a medium heat and bring to the boil. Take off the heat immediately, place a lid on the pan and leave for 10 minutes to cook. Run the eggs under cold water and peel them, then transfer to a large bowl.
Step 2
Use a fork to gently break the eggs up (don’t mash them). Add the mayonnaise, spring onions and cornichons. Season and fold everything together gently, then set aside.
Step 3
Put all the dressing ingredients into a small jar and shake hard to mix well.
Step 4
Fill your chosen bread with the egg mixture and lettuce leaves, or serve as a salad. Either way, sprinkle the toasted seeds on top of the egg mayo and drizzle with the dressing.
