For the Ham Loaf:

1. Preheat the oven to 375 degrees F.  Line a rimmed baking sheet with aluminum foil and spray it well with cooking spray.
2. In a large skillet, cooked the onion until translucent and just beginning to brown, about 5 minutes.  Remove from heat and allow to cool slightly.
3. In a large bowl, combine all the ingredients, including the slightly cooled onion.   Mix with a large spoon (or your hands) until fully incorporated.
4. Shape into a meatloaf and bast with a little glaze.
5. Bake for 55 minutes, basting top of ham loaf with glaze every 30 minutes or until internal thermometer reads 155-160 degrees F.  Allow the meatloaf to cool slightly before serving.

For the Glaze:

1. Combine the ingredients in a medium-size bowl or 4 cup glass measuring cup and whisk the ingredients together.  Cook in the microwave for 1 minute intervals, stirring in between each minute, until the mixture thickens (should take approximately 3-5 minutes).  Set the glaze to the side.
