Preheat oven to 350° Fahrenheit. Break dry ramen noodles into small pieces, then arrange broken noodles, 3 ounces slivered almonds, and sesame seeds on large baking sheet.
Place baking sheet in preheated oven. Bake ingredients 10 minutes or until just browned. Once browned, carefully remove baking sheet from oven and set aside to cool completely.
While baking ingredients, add ½ cup avocado oil, ¼ cup granulated sugar, 3 tablespoons red wine vinegar, and seasoning packet to medium mixing bowl. Whisk ingredients together until fully incorporated.
Cover bowl and refrigerate dressing mixture until ready to serve.
Once toasted almonds and noodles have cooled, add noodles, almonds, sesame seeds, 1 16-ounce bag coleslaw mix, 1 cup chopped green onions, and 2 small mandarin oranges to large mixing bowl. Toss salad until ingredients are well blended.
Pour chilled dressing over slaw mixture. Toss until slaw mixture is fully coated in dressing. Serve immediately.
