Place the roast in the base of the slow cooker, season with minced onion, salt and pepper. Add about 1/2 cup of water around the roast. (I do this to make the atmosphere inside the slow cooker nice and moist while the pork cooks.)
In a small bowl, whisk together the peach preserves and ginger. Spread over top of the pork roast.
Set the slow cooker on low and cook for 8 hours.
Prepare the brown rice and green beans as directed.
