1. Preparation
Gather all the ingredients before starting.
Peel and devein 300g of shrimp and pat them dry with paper towels.
Dice 1 bell pepper and 1 medium onion into small pieces.
Chop 2 green onions and set them aside for garnish.
Roughly chop 50g of unsalted roasted peanuts.
Prepare a marinade by mixing 1 tablespoon of soy sauce, 1 tablespoon of rice vinegar, and 1 teaspoon of cornstarch in a bowl. Add the shrimp and let them marinate for 15 minutes.
2. Cooking
Heat 2 tablespoons of vegetable oil in a large skillet or wok over medium-high heat.
Add the marinated shrimp to the pan and stir-fry until they turn pink and are just cooked through, about 2-3 minutes. Remove the shrimp from the pan and set aside.
In the same pan, add another tablespoon of oil if necessary. Add the diced bell pepper and onion, stir-frying for about 2-3 minutes until they start to soften.
Add the chopped peanuts to the pan and stir-fry for another minute.
In a small bowl, combine 2 tablespoons of soy sauce, 1 tablespoon of sugar, 1 tablespoon of rice vinegar, and 1 teaspoon of chili paste. Pour this mixture into the pan and stir well to combine.
Return the shrimp to the pan and toss everything together, cooking for an additional 2 minutes until heated through.
Garnish with chopped green onions before serving.
