Whisk together all dressing ingredients to combine well. Cover and chill until ready to use. May be prepared up to several days ahead of time. Re-whisk right before using.
For the Salad
Crumble the dry ramen noodles into small pieces. Set aside.
In a large heavy skillet, melt butter on medium high heat. Add dry ramen pieces, sliced almonds, and sesame seeds. Add 1 seasoning packet and stir well to combine. Continue to stir mixture until golden, but be careful not to burn it, about 1-3 minutes. Transfer to a serving container and set aside to cool completely.
When ready to serve, toss cole slaw mix, edamame, and green onions in a large serving bowl. Drizzle with dressing and toss to coat well. Sprinkle with some of the crispy ramen mixture. Serve immediately, with remaining crispy ramen mixture on the side, to keep topping crisp while people help themselves.
Notes
Ramen noodles in package are already pre-cooked and dried, so don't worry that it's "uncooked." I prefer to use 1 seasoning packet in my salad; feel free to either throw out the 2nd seasoning packet or go ahead and use it for extra flavor. Tip: Make extra dressing to keep in fridge so you can use it on other salads.
