What’s in a Tuna Mayo Sandwich?
Wholemeal Bread – Wholemeal bread is a fantastic source of complex carbohydrates, which are key for sustained energy. Unlike refined grains, wholemeal bread contains fibre that helps with digestion and provides a steady release of energy.
Tinned Tuna – Tuna is packed with lean protein, which is essential for muscle repair and recovery after training. It also contains omega-3 fatty acids, which reduce inflammation and support cardiovascular health.
Sweetcorn– While it may not offer enough in the tuna mayo sandwich recipe to count as 1 of your 5-a-day, sweetcorn adds a touch of natural sweetness. It also helps provide a source of healthy carbs and antioxidants.
Cucumber – Cucumber helps to maintain hydration levels. It’s low in calories but rich in vitamins and minerals. It also adds a crisp texture to an otherwise softer sandwich.
Lite Mayo & Herbs (Parsley & Dill)– While mayonnaise adds healthy fats for energy, parsley and dill enhance the flavour. At the same time, they help fight oxidative stress caused by intense exercise.
