There is no need to blanch shredded cold lettuce in advance. The method is as follows:

1. Ingredients: lettuce, red pepper, garlic, salt, sugar, mature vinegar, and chili oil. First, wash the lettuce, peel it and cut it into thin strips. Wash and cut the red pepper into shreds. Put all the cut lettuce and red pepper into a basin and soak them in cold water for a while.

2. Peel and mince the garlic, put it into another clean container, stir evenly, then add an appropriate amount of salt, sugar, mature vinegar, and chili oil for seasoning, and then add a spoonful of it to it. Warm water and mix thoroughly. Friends who don't like spicy food can choose not to add chili oil or add it according to their own discretion.

3. Take out the soaked lettuce shreds and red pepper shreds, drain the water, pour in the sauce you just prepared, mix the ingredients and sauce thoroughly, and finally take them out and serve on a plate. .
