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.
