My son is autistic and a very picky eater. But his favorite food is pumpkin pie. So peeled and sliced some sweet potatoes. Laid them on a baking sheet sprinkled some cinnamon ginger and brown sugar on them and baked them. When I put it on his plate I told him they where baby pumpkin pies and that there where dessert and had to eat them last. It worked he cleared his plate and gobbled them up.
That's awesome, my adult autistic daughter is pretty much addicted to pizza and I hate it. Spaghetti is the healthiest thing she eats. I'm going to try and feed her the sweet potatoes like you did. Wish me luck.
