First things first, get all your beautiful veggies ready. Combine the shredded cabbage, red cabbage, carrots, cucumbers, red pepper, green onions, steamed edamame, bean sprouts, and chopped serrano pepper (if using) in the largest bowl you own. Seriously, you'll need space to toss!
Now, let's make that magical dressing. Grab your blender, food processor, or immersion blender. Add the peanut butter, rice vinegar, lime juice, maple syrup, sesame oil (if using), sriracha or sambal, soy sauce or tamari, your peeled fresh ginger, the garlic clove, and start with 2 tablespoons of water. Blend it all up until it's silky smooth. If it's too thick to pour easily, add water one tablespoon at a time until it reaches your desired consistency. Taste it and adjust if needed – maybe a little more lime, a touch more sweetness, or extra sriracha if you're feeling bold!
Time for the garnish prep! Chop up your fresh herbs – cilantro, basil, mint, whatever you love. Chop your roasted peanuts and/or sunflower seeds. Now, for the ramen crunch: break up a block of plain ramen noodles (discard the seasoning packet!) into small pieces. You can toast them in a dry pan over medium heat for a few minutes, stirring often, until they're golden brown and fragrant, or even spread them on a baking sheet and pop them in a moderate oven (around 350°F / 175°C) for 5-10 minutes. Keep a close eye on them so they don't burn! Let them cool completely.
Hold off on dressing the salad until you're ready to eat! When it's serving time, pour the creamy peanut dressing over the big bowl of chopped veggies. Use tongs or salad servers to gently toss everything together, making sure every single piece gets coated in that delicious sauce.
Divide the dressed salad among plates or serve it directly from the bowl. Just before serving, generously sprinkle the chopped herbs, nuts/seeds, and those glorious toasted ramen pieces over the top. Get ready for that amazing crunch!
