Preheat your oven to 400°F.

In a shallow bowl, whisk together the egg and water.

In a food processor, pulse the cashews into a coarse flour, not too fine. Add the salt, garlic powder, oregano, paprika, and pepper. Pulse once again just to incorporate the spices into the crumbled cashews. Place this mixture in another shallow bowl.

Set up a workstation in this order: the bowl with the egg wash, the bowl with the cashew blend, and a foil or parchment-lined sheet pan.

Dip a chicken breast into the egg wash and then coat with the cashew mixture. Place the coated chicken on the sheet pan. Repeat until all the breasts are coated.

Place the pan in the oven and bake for 20 to 25 minutes or until the internal temperature reads 165°F when checked with a digital meat thermometer. The outer coating should be golden brown.

Remove the chicken from the oven and allow it to rest for 5 minutes. Serve with your favorite side dishes.
