Step 1

Combine tomato sauce, honey, soy sauce, vinegar, sugar, mustard and salt and pepper in a ceramic dish. Add ribs and turn to coat. Cover and refrigerate for at least 1 hour.

Step 2

Preheat oven to 200°C. Line a baking tray with baking paper. Place ribs on tray. Roast for 1 hour, turning ribs over once, or until cooked through.

Step 3

Meanwhile, place a wire rack over an oven tray lined with paper towel. Pour oil into a large saucepan until one-third full. Heat over medium-high heat until hot. Cook potato slices, 5 or 6 at a time, for 2 to 3 minutes or until golden. Drain on wire rack.

Step 4

Serve ribs with potato crisps and spinach.
