Low and slow - since the food cooks slowly over a long period of time, it keeps the moisture in the food so you don't need to add a lot of unhealthy ingredients, like fats and extra salt. Flavor - It also tends to make the food more flavorful so you are more likely to eat a healthier option that tastes better than a quick option, which is usually not as healthy. Veggies - it's so easy to throw a few extra veggies in your dish and by the time they are cooked, they aren't even recognizable to most children. And even if they are, they are nice and soft and small and they will usually eat them.
