Baked Beans with Ground Beef

Heat oil in a large saucepan over medium-high heat. Add onion and ground beef. Cook, stirring and crumbling beef with a wooden spoon, until the onion has softened and the beef is no longer pink, about 5 minutes. Add beans, water, ketchup, molasses, mustard, garlic powder and salt; bring to a simmer. Reduce heat to medium and cook, stirring, until the mixture is bubbling and slightly thickened, 5 to 8 minutes. Garnish with chives, if desired.
