It's best to prepare the first part of the recipe the day before and then add the poppy seed, veggies, sauce and garlic the same day. Cook the spaghetti noodles al dente (you want them to soak up some of the marinade. Rinse, strain and cool. Combine with the whole bottle of Italian dressing, vinegar and whole bottle of salad supreme seasoning. Easiest to mix with your hands. Mix well and refrigerate which allows the noodles to marinate. A few hours before serving, add the remaining ingredients. Once again, it's easiest to mix with your hands. I also add more poppy seed and garlic to this recipe. I prefer to chop the veggies on the small side. They seem to mix better than way.
