Step 1

Preheat oven to 350°.

Step 2

Mix together the ground beef, bread crumbs, onions, parsley, garlic, parmesan, egg, and milk.

Step 3

Pour half of the sauce into a 9x13 inch pan.

Step 4

Gently stuff the beef mixture into the manicotti noodles, and place them into the pan. Repeat until all the shells are filled.

Step 5

Pour 3/4 cup water into the jar of sauce with half remaining, shake the jar to mix it up, and top with the sauce, and slices of mozzarella cheese.

Step 6

Cover the pan tightly with non-stick foil, or foil that's been sprayed well with cooking spray.

Step 7

Bake at 350 for 45-55 minutes. For slow cooker, cook on high for 2 - 2 1/2 hours, depending on your model. Make sure the meat gets above 160 degrees.

Step 8

When the manicotti has been in the oven for about 30 minutes, place your spinach into a saute pan with 1-2 tablespoons of olive oil and 1 teaspoon minced garlic over medium heat until it is completely thawed and any excess water has cooked off.

Step 9

Add the cream, chicken stock, and nutmeg, and simmer for 5-10 minutes, or until reduced and slightly thickened.

Step 10

Serve the manicotti on top of a bed of the creamed spinach with a good crusty garlic bread and a green salad.
