Prepare the Quinoa: Start by thoroughly rinsing the quinoa under cold running water using a fine-mesh strainer. This removes the natural bitterness. In a medium saucepan, combine the rinsed quinoa with one cup of water. Bring to a boil over medium heat, then reduce to a gentle simmer and cover. Cook until the water is fully absorbed and quinoa is tender, about 15 minutes. Remove from heat and let it sit covered for 5-10 minutes to steam. Fluff the quinoa lightly with a fork and set aside to cool. Combine the Salad Vegetables: In a large mixing bowl, add the shredded cabbage blend, snap peas, sliced red bell pepper, green onions, chopped cilantro, and roasted peanuts. Sprinkle in the sesame seeds, then gently fold in the cooled quinoa, ensuring everything is evenly mixed.
Whisk the Dressing: In a small bowl, whisk together the peanut butter, coconut aminos, lime juice, rice vinegar, toasted sesame oil, minced ginger, garlic, red pepper flakes, and sea salt until smooth. If the dressing feels too thick, add warm water one teaspoon at a time until it reaches a pourable, creamy consistency.
Toss and Serve: Pour the prepared dressing over the salad ingredients. Gently toss everything together until the salad is evenly coated with the dressing. Serve immediately, garnished with extra chopped peanuts, fresh cilantro, and lime wedges for squeezing.
