Whisk 1/2 cup vegetable oil, 1/3 cup rice vinegar, 3 tablespoons sugar, 2 tablespoons soy sauce and 2 teaspoons toasted sesame oil in a large bowl. Break two 3-ounce packages ramen noodles into bite-size pieces (discard the seasoning packets). Add the uncooked ramen to the vinaigrette along with one 16-ounce bag broccoli slaw mix, 1 cup julienned snow peas, 3/4 cup toasted slivered almonds and 4 chopped scallions. Season with salt and pepper and toss. Let sit 1 to 2 hours before serving.
