1。 Replace tomatoes with cherry tomatoes, lay them flat in the middle and cut both sides. 2。 The reason why lettuce is bitter is that I bought it wrong. I have to go to a large supermarket to buy the kind with core and heavy hands, peel it off and tear it into small pieces of 10CM*3CM. Just pat the whole cucumber flat with a knife, don't smash it. Fasten the middle bag and cut it into 2CM*2CM cubes (the whole cucumber should be scraped with a knife, and the thorns on it are bitter). Put everything in a large bowl, sprinkle with half a teaspoon of salt, then squeeze 1/4 lemon juice, 1 teaspoon sesame oil and two chopped parsley salad dressings. Cupid salad dressing is recommended (I've tried it)
