Preheat your oven to 350°F.
Spread noodles, almonds, and seeds on a baking sheet.
Melt butter and drizzle over the mixture evenly.
Bake for 10 minutes, stirring halfway through for even toasting.
Remove from oven and cool completely.
In a saucepan, combine vinegar, sugar, and soy sauce.
Bring to a simmer and stir until sugar dissolves.
Remove from heat, let cool, and whisk in the oil.
In a large bowl, combine cabbage and green onions.
Add the cooled noodle mixture on top of vegetables.
Pour dressing over and toss everything until well coated.
Chill in the fridge for at least 30 minutes.
