Crush noodles, place them in a medium skillet and brown in butter over medium heat. Add almonds and sesame seeds. Stir often to prevent burning. Add seasoning mix from noodles and cool. Toss in a large bowl with cabbage and onions.
Prepare the dressing by whisking together the vegetable oil, rice vinegar, soy sauce, sesame oil and sugar. Pour over salad, toss and serve.
