In a small bowl, combine very well all the “Sauce” ingredients. Set aside.
Boil some water in a saucepan over high heat. Place in tamarind and cook for 3 minutes. Strain well to remove any seed.
Pour the tamarind juice back to the pan. Bring it to a rapid boil; add some sugar and salt. Place in beef slices; cook for few seconds, and remove the beef. (You can cook your beef fully cooked or medium rare if you prefer to)
Place the cooked beef into a big bowl with the rest of sliced yellow onion, sawtooth herb. Then pour the sauce over the salad. Mix up
Transfer to a dish. Garnish with fried garlic and crushed peanuts. Deco with cherry tomato that I’ve already cut into flower shape and with some mints.
Arrange the shrimp chips around the salad. It can be served with shrimp chips.
