To make the dressing: Combine the oil, 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 the butter is melting, crush the ramen noodles while still inside the package. Remove the seasoning packet and discard. Add the noodles, almonds, and sesame seeds to the melted butter.
Saute while stirring frequently, until the noodle mixture is golden brown. Remove to a plate and let cool.
Shred the cabbage and combine with sliced green onions in a large bowl. Add the cooled noodle mixture. Pour the dressing over the salad and toss to combine. Garnish with additional green onions if desired.
