Put the ramen noodles in a bag and crush them with a rolling pin while melting butter in a large skillet over low/medium heat. Add the crushed noodles and slivered almonds to the skillet and saute, stirring occasionally (keep temperature at low/medium heat). Meanwhile, whisk together all the dressing ingredients in a small bowl. Place the shredded broccoli into bowl and toss with the noodles, almonds, and sunflower seeds. Pour dressing over salad and toss to coat. Garnish with chopped green onions.
