don't toss them, there's a ton of nutrition in those skins. toast them, grind into powder, and stir into baking recipes or oatmeal...or even yogurt. they're a great source of fiber, prebiotics & antioxidants.
You could mix them in with cookie dough or something like pancake or waffle batter. That's not a recommendation (I'd just toss 'em out) but it's a method that will serve the purpose you describe.
