Place almond flour and all spices in a shallow bowl. Mix well.
Place egg whites in a separate shallow bowl and mix with sriracha.
Dip pickle slices in egg whites, then coat in almond flour mixture on both sides. Place on a cooking sheet lined with parchment paper.
Bake for 20 minutes. Turn heat onto broil and place pickles back in the oven for 5 minutes. Flip to other side and place in oven for another 3 minutes, or until outsides are crispy.
