A delightful spinach salad with a tangy and sweet poppy seed vinaigrette, perfect for any occasion.
Combine the vinegar, sugar, poppy seeds, dry mustard, salt, mayonnaise, and finely chopped red onion in a mixing bowl.
Whisk the ingredients thoroughly to ensure the sugar dissolves completely.
Cover the dressing and refrigerate it overnight to allow the flavors to meld.
Chilling the dressing enhances its flavor and consistency.
In a salad bowl, combine the spinach, sliced mushrooms, shredded Swiss cheese, crispy bacon pieces, and sliced almonds.
Ensure the spinach is dry to prevent the dressing from becoming diluted.
Pour the desired amount of dressing over the salad and toss gently to coat.
Add the dressing gradually to avoid overdressing the salad.
Serve the salad immediately and enjoy.
Garnish with extra almonds or a sprinkle of cheese for presentation.
