Zesty Ham and Pineapple

To make the sauce, whisk the mustard, maple syrup, oil, 5-spice powder, and soy sauce (if desired) in a small bowl. Cut the ham into individual portions and use a pastry brush to spread the mustard mixture on both sides of each piece (another great job for kids). Grill the ham 5 or more minutes on each side until it heats through. Grill the pineapple slices at the same time and serve them atop the ham. Makes about 6 servings. Do-ahead Tip for Campers: Mix the mustard sauce at home and seal it in a small plastic container that can be packed in your cooler. You can also cut the ham into servings and pack them in a sealable plastic bag.
