"Pickled carrot and daikon radish can be found in Korean, Vietnamese, and Japanese cuisine. Combined with rice in this cool, light and flavorful salad, it will remind you of sushi and rice rolls. Shrimp or crab can be added to make this into a main dish salad."
Whisk rice vinegar, sugar, and 1/2 teaspoon salt together in a bowl; add carrots and radish and stir until well-coated. Cover the bowl with plastic wrap and refrigerate, stirring occasionally, until flavors blend, at least 1 hour. Drain.
Bring water and rice to a boil in a saucepan. Reduce heat to medium-low, cover, and simmer until the rice is tender and liquid is absorbed, 20 to 25 minutes. Spread rice out on a baking sheet and cool to room temperature.
Whisk vegetable oil, lime juice, ginger, sesame oil, garlic, chile paste, and remaining salt together in a large bowl. Add rice, drained carrot mixture, cilantro, peanuts, and green onions to the bowl; stir until salad is well-coated. Serve warm or cold.
