Low-Calorie Meatloaf with Spaghetti Sauce

Why this version is better

Calorie reduction of ~54% per serving, falling just under the 400 kcal target. Fat drops by ~69%, primarily saturated fat. Carbohydrates drop by ~56%. Protein is largely preserved (~92% retained) keeping the meal highly satiating. Zucchini noodles add micronutrients (Vitamin C, potassium) and fiber with negligible caloric cost. No allergen profile changes.

Cooking note: Replacing wholemeal spaghetti (the single largest calorie contributor at ~330 kcal/serving) with zucchini noodles eliminates the dense starch load entirely while preserving the serving vessel role. Swapping mature cheddar for a light sprinkle of reduced-fat Parmesan (used in smaller quantity) cuts fat significantly while maintaining the savory, melty topping; Parmesan's stronger flavor means less is needed. The pork mince is replaced with extra-lean turkey mince (1–2% fat) which is structurally similar for loaf-binding purposes — the egg and oats still provide sufficient cohesion, so no instruction changes are needed for texture.
