Stuffed Zucchini Boats

I found this recipe in Good Housekeeping:

SAUSAGE STUFFED ZUCCHINI BOATS

• 4 small zucchini
• 2 tsp. olive oil
• 1 small onion, chopped
• 2 links sweet Italian sausage, casing removed
• 1/4 tsp. salt
• 1 1/4 c. marinara sauce
• 1 c. shredded mozzarella
• Chopped parsley
• pasta

1. Cut zucchini lengthwise in half; scrape out and chop flesh, leaving 1⁄4 inch shell.
2. In 10-inch skillet, heat olive oil on medium-high. Add chopped zucchini, onion, sweet Italian sausage, and salt. Cook 8 minutes, breaking up with back of spoon.
3. In 3-quart baking dish, spread marinara sauce; arrange zucchini shells on top, cut sides up. Spoon sausage mixture into shells. Top with shredded mozzarella. Cover with foil; bake in 450°F oven 30 minutes. Uncover; bake 5 minutes. Garnish with parsley. Serve with pasta.

I used left over meatloaf (instead of sausae) and some of my own leftover spaghetti sauce but followed the rest of the recipe closely.  VERY GOOD!
