Pork Roast with Caramelized Onions

1 large Vidalia or other sweet onion, sliced
2 tbl olive oil
2 tbl sugar
2-lb boneless pork loin, seasoned with black pepper and garlic

I cook this in my Nesco oven.
Preheat the oven to 400. When it's hot, place the pork loin into the roaster and turn it down to 300.

Heat a heavy skillet and add oil. Add onions and sugar. Stir to coat. Cook for 30 minutes, stirring occasionally, until onions are brown and caramelized. Use tongs to place the onions on top of the pork roast and continue cooking until the roast is done (usually about 1 1/2 hours). Use a meat thermometer to verify doneness.

To make in a regular oven, use a foil "tent" over the pork roast after adding the onions.
