I got this recipe from my mother-in-law, who says these were my veggie-hating husband's favorite childhood snack. They are a great way to get kids to eat spinach!! Prep time includes chill time. This can be a little salty depending on the butter, cheese and bread crumbs you use, if you are concerned about saltiness use unsalted butter and garlic powder in place of the garlic salt. I have also made these with only 1/2 cup of melted butter (1 stick) and they are just as good but you need to spray the cookie sheet because they will stick.
