In a medium saucepan, melt butter over medium heat. Cook and stir almonds in butter until lightly toasted. Remove from heat, and let cool.
In a medium bowl, whisk together the sesame seeds, poppy seeds, sugar, onion, paprika, white wine vinegar, cider vinegar, and avocado oil.
In a large bowl, combine the spinach with the toasted almonds and cranberries and toss with the dressing.
Notes
*Add as little or as many cranberries as you like. The original recipe calls for 1 cup, but I think that's too much. **The original recipe uses vegetable oil, which is fine to use if you can't find avocado oil.
