Spinach-stuffed Turkey Meatloaf

This is really, really tasty. It's also low-fat. I didn't have ground turkey, so I used the ground chicken I had on hand. Make sure to let the meat sit in the fridge for at least an hour after you press it into the pan so you can roll it easily.

Meat mixture:
3 slices bread, crust removed
1/2 c. milk
1 lb. ground chicken
1 tbsp. Dijon mustard
1 egg white
1 tsp. oregano
Fresh ground pepper

Line a rimmed baking sheet with foil. Spray the foil with cooking spray.
Tear bread into 1 inch pieces. Put in a bowl, pour in the milk and mash the bread with a fork until all the milk is absorbed.
In another bowl, mix the chicken, mustard, egg white, oregano and pepper.
Add in the bread mixture and mix well, until creamy.
Press the meat mixture onto the baking sheet so that it covers 1/2 the baking sheet
Place in the refrigerator for at least one hour (up to three hours)

Filling:
1 10 oz. package of frozen spinach
3 green onions, chopped (green part only)
1 egg white
Fresh ground pepper
1 tbsp. olive oil
Parmesan cheese, grated, about 1/3 cup

Thaw and drain spinach. Press out all the water.
Heat olive oil in a skillet. Add the spinach and onion and cook until mixture is somewhat dry and the onions begin to wilt, about 5-6 minutes.
Remove from heat and allow to cool. Mix in egg white and season with lots of pepper.

Preheat oven to 350.
Remove baking sheet from fridge.
Spread the spinach mixture over the meat, leaving 1 inch border all the way around.
Sprinkle the cheese over the top.

Place baking sheet horizontally.
Starting at the end closest to you, use the foil to lift the meat and roll jelly roll style, pushing forward a little bit at a time.

Bake at 350 for about an hour, until a thermometer registers 160. Serve with tomato sauce.
