Very thick-sliced bread (I use Japanese 8-sliced sandwich bread)
My favorite seasonings:
Your favorite type of bread
Coarsely ground black pepper
Don't put any sugar.
I don't like sweet egg-based sandwiches
Rinse the cucumber and chop roughly. Sprinkle with a little salt and let it sit for about 10 minutes. After 10 minutes, squeeze out the excess liquid.
How to mash the boiled eggs nicely.
Refer to Cookpad user MOMO's recipe (Recipe ID: 404007).
Boil the egg and mash into a size similar to the cucumber.
Mix the cucumber and egg.
Stir in the mayonnaise and a little sugar (I use coarsely ground black pepper instead of sugar). Mix well.
Mix and season to your liking.
Spread mustard and butter on the bread and then the cucumber and egg mixture. Don't put any mustard if you make this for your children.
Too easy, right?! You're all done!
Story Behind this Recipe
Eating these always make me nostalgic for school lunches. It's an easy, relatively simple sandwich but I have never seen this anywhere else so I posted this recipe. My sister, who went to the same school, says 'I don't remember this.' I wonder why. A lot of people seem to like it anyway!
The cucumber is prepared with salt, so don't use too much mayonnaise. When I was an elementary school student, I used to think that the mustard in mine was too strong so you might not need any mustard for your children's sandwiches. I think these are easier to eat than regular egg and sliced cucumber sandwiches.
