1. Put 4 spoonfuls of soy sauce and 2 spoonfuls of balsamic vinegar into a bowl, and mix into sauce for later use.

2. Tomato peeling method: cut a cross on the surface, put it in a boiling pot and take it out, which will peel it well. Dice tomato, 1/4 shredded cucumber and 16g shredded ham. If you like coriander and pickled peppers, you can prepare 2 chopped coriander and 5 pickled peppers.

3. Add oil to the pot, stir-fry diced tomatoes on low heat until the sand comes out, turn off the heat when the state is soft and rotten, and add a little salt to taste.

4. 150g noodles are put into boiling water, boiled for about 2 minutes on low heat, and taken out. Take out the noodles in ice water and put them in a bowl.

5. Spread shredded cucumber and shredded ham on the noodles (if you like coriander and pepper, you can add them yourself), pour sauce and fried tomatoes, and squeeze some green lemon juice to complete the tomato and ham cold noodles!
