1. Step 1

   Place spinach in a microwave-safe bowl. Add 1 tablespoon water. Cover with plastic wrap. Microwave on HIGH (100%) for 1 to 2 minutes or until just wilted. Set aside to cool. Squeeze out excess water.

2. Step 2

   Place mince, garlic, oregano, egg and breadcrumbs in a bowl. Season. Mix well.

3. Step 3

   Place a sheet of baking paper on a flat surface. Place mixture onto paper, pressing to form a 25cm x 28cm rectangle. Leaving a 1cm border, arrange spinach on top. Spread with ricotta. Sprinkle with mozzarella. Dollop with relish. Top with pepper, then basil. Using paper as a guide, roll up mince from 1 long end to enclose. Press ends to seal.

4. Step 4

   Pour 1/2 the pasta sauce into slow cooker. Place meatloaf, seam-side down, into sauce. Pour over remaining sauce. Season.

5. Step 5

   Cook on high for 4 hours (or low for 6 hours) or until meatloaf is cooked through. Turn slow cooker off. Stand for 10 minutes. Lift meatloaf onto a board. Slice. Serve with sauce, salad, parmesan and bread.
