Ingredients for 8 servings:
1. 1 tablespoon canola oil or 1 tablespoon olive oil, if you wish
2. 1 (4 lb) boneless pork loin roast
3. 1/2 teaspoon salt
4. 1/2 teaspoon fresh ground black pepper
5. 1 medium onion, sliced into thin rings
6. 6 garlic cloves, minced
7. 1/4 teaspoon poultry seasoning
8. 1/4 cup white wine or 1/4 cup apple juice, although that gives a different flavour
9. 4 cups cubed sweet potatoes (peeled, cut into about 1-inch cubes)
10. 1 cup chicken broth

Directions:
1. If there is a lot of visible fat on the pork roast, trim it away.
2. In a large, heavy skillet, heat oil over medium-high heat.

4. Remove browned roast to a plate and temporarily set aside.
5. In fat in skillet (add a little extra oil if needed), saute sliced onion and minced garlic, seasoned with the poultry seasoning, just until onion starts to soften; place in bottom of slow cooker.
6. Turn heat to high and add white wine to skillet; scrape up all the bits sticking to skillet (in other words, deglaze the pan), then pour this mixture over the onions in the crock pot.
