I sprayed them with a little bit of olive oil. You can also use this method to evenly oil leafy greens like kale. I actually baked few batches. Maybe the type of the kale I had in my backyard has already salty flavor. When I added salt, the taste of the first batch was too salty for me. So in the later batches, I sprinkled just a few pinches. I laid the pieces on a natural parchment paper on an oven tray.
In my opinion, they turned out great. They were crispy and salty enough to make you keep eating until the whole batch was gone. I want to try this recipe with different spices and herbs. It’s is such a tasty snack.
