To make the dressing: Combine the light olive oil, white vinegar, sugar, and soy sauce in a jar and shake until the sugar has dissolved.
Melt the butter in a large skillet over medium heat. While melting, crush the ramen noodles in their package and remove the seasoning packet.
Add the crushed noodles, slivered almonds, and sesame seeds to the melted butter. Sauté, stirring frequently, until golden brown. Remove from heat and let cool.
Shred the cabbage and combine it with the sliced green onions in a large mixing bowl. Add the cooled noodle mixture.
Pour the dressing over the salad and toss well to combine. Sprinkle with additional green onions if desired and serve immediately.
Notes
This salad is best served immediately but can be refrigerated for a few hours. The noodles will soften over time.
