Combine the cherry juice, water and dried cherries in a small bowl and set aside so the cherries plump up.
Meanwhile, add the green beans to a large skillet with about 1/2 a cup of water. Cover, bring to a boil and let cook 1 minute. Drain the green beans, rinse them with cold water to stop the cooking process and set aside.
Return the skillet to the stove over medium heat and melt the coconut oil in it.
Once hot, add the onion and ham and let cook for about 10 minutes until the onions start to caramelize and the ham becomes golden and crispy.
Pour half the liquid from the bowl with the cherries into the pan and scrape up any bits that are stuck to the bottom with a wooden spoon. Let the liquid cook off (about 1 minute) and add the green beans to the skillet.
Toss to combine, add the plumped cherries, season with salt and pepper and top with the feta.
