My husband is a pistachio addict. He loves pistachios. I buy them EVERY time I go to the grocery. He cannot get enough of them, really its an obsession. He eats them shelled, unshelled, plain, salted, spiced you name the packaging and he will eat it. I could not wait to incorporate these tasty little nuts into a delicious recipe. I scoured the internet for recipes and came up empty-handed. I needed a recipe that incorporated pistachios and would satisfy my husbands peculiar taste palate. He would be a happy camper if we could have steak and a form of cooked potatoes every night. Thus, the Pistachio Chicken Carbonara recipe was created.
