Combine the green onions and cabbage in a large bowl, cover, and refrigerate until ready to serve.
To Make Crunches
Melt the butter in a non-stick pan.
Mix the ramen noodles, sesame seeds, and almonds in the pan with melted butter.
Saute until the mixture starts to lightly brown. Stirring continuously.
Add sugar to toasted noodle mixture, stirring constantly. Continue to cook until caramelized, about 5 minutes
To Make Dressing
In a small saucepan, heat vinegar, oil, sugar, & soy sauce.
Bring the mixture to a boil, let boil for 1 minute.
Remove the pan from heat and let cool.
Right Before Serving Salad
Combine dressing, crunchies, and cabbage immediately before serving. Serve right away or the crunchies will get soggy.
Notes
This napa cabbage ramen salad does not refrigerate well or keep. I suggest you keep the salad mix, crunchies, and dressing separate until ready to serve.
