In a large mixing bowl, add egg whites and honey and whisk them until soft peaks form (not stiff peaks).
In another mixing bowl, whisk together almond meal, sugar, vanilla extract, almond extract, lemon zest until combined.
Add this flour mixture to the egg mixture.
Mix gently until combined.
Cover and chill in fridge for about 1-2 hours to make it less sticky and easier to handle.
Scoop out small portions of the dough and roll them into oval shapes. You can also make round balls, if you prefer that shape but typically they are oval shaped.
Next, roll them in a bowl of sliced almonds until fully coated.
Place them on a cookie tray, lined with parchment paper.
Bake at 320 degrees F for about 20 minutes or until tops are golden brown.
Remove from oven and allow the cookies to cool completely in the tray.
Dust a bit of powdered sugar on top prior to serving, if you like. Enjoy!
