Whisk together the ingredients for the dressing and taste for seasoning, adding more salt/pepper if needed.
Combine all ingredients for salad in a large bowl: kale, sliced strawberries, almonds and shaved manchego.
Right before serving, toss dressing with salad and serve.
Notes
If you don't have lavender sugar, you can crush 1/2 teaspoon lavender with 1 teaspoon sugar to make your own. While you can omit it, I think it gives a lovely floral flavor that works perfectly with the strawberries and poppyseeds.
