Melt the butter in the saucepan. Toast the almonds in it over medium heat. Remove from the heat and let them cool down in a separate bowl.
Add the spinach to the salad bowl. Add almonds and cranberries to the spinach and toss well to combine.
Prepare the dressing in a small mixing bowl. Whisk together the sesame seeds, poppy seeds, sugar, onion, paprika, white wine vinegar, cider vinegar, and vegetable oil. Right before serving, pour the dressing over the spinach and toss well. If you pour the dressing a long time before serving, the spinach will loose its freshness.
You can also try variations by adding blue cheese and apples according to your taste. This is a recipe that is going to keep your guests raving until the next invitation to your place reaches them.
