I’ve always bought “healthy” snacks. My cupboards were full of GMO-free chips made with Himalayan salt and seaweed packets flavored with organic soy sauce. But at roughly $4 a pop, those packaged snacks added up—especially when my teenagers devoured a bag in one sitting. I was tired of the whining, “We don’t have anything to eat…” just a few days after I’d gone to the market. “Grab an apple!” I’d tell them, but they’d just shake their heads, rummaging through the shelves for a wayward packet of flaxseed crisps. They were addicted to the salt and the crunch of packaged snacks. And it had to stop.
