Lots of options.
You could boil the potatoes then saute them in butter with fresh parsley, salt & pepper. Roasted is always good. Especially if the oven is already going to be on (for the ham). And roasted asparagus is always good. I like mine with EVOO and I've been on a lemon pepper kick lately. I love lemon pepper on asparagus. The easiest way to cook asparagus though is probably either boiling or microwaving. Just some butter on the cooked asparagus and you're good to go. Or you could even cut them into pieces (diagonal cuts, or on the bias always looks nice) and make a white sauce for some creamed asparagus. With a little smoked paprika... mmmm... Just don't forget to get rid of the woody end. Snap one and see where it breaks, then hold it up against the rest and cut that much off the ends of all of them. Or snap them all. Whatever you feel like doing, lol. My one dog can hear me snapping asparagus from the other room
I would definitely try to balance out the sweetness of the ham's glaze and the other veggies you are going to glaze.
