Loaded Sweet Potato Nachos with Zesty Guacamole. Nachos! They’re usually just an occasional treat for most people, as they aren’t exactly waistline friendly. This version of nachos, however, is highly nutritious for your skin and body. The sweet potato caramelises in the oven, becoming chewy with crispy edges, while the zesty guacamole adds a delicious twist. Sweet potatoes are a true superstar root vegetable and a good complex carbohydrate to enjoy in your diet frequently. They’re also a great source of beta-carotene, which is important for eye and skin health and for a glowing complexion. They contain fibre, potassium, calcium and magnesium, plus vitamin C necessary for collagen production in the skin and vitamin B6 to boost your mood. They’re a true feel-good food for health and beauty. This recipe is from Rosanna Davison’s ‘Eat Yourself Beautiful’ cookbook.
