Boiled beetroot with a touch of vinegar, egg mayo and a stick of cheddar. Garnished with coriander because I like my lunchboxes to look good.
Beetroot : If you’re considering beetroot as one of your 5-a-day, it contains potassium, magnesium, iron, vitamins A, B6 and C, folic acid, carbohydrates, protein, antioxidants and soluble fibre. http://www.webmd.boots.com/healthy-eating/beetroot-benefits
Eggs: don’t beat yourself up. Eggs just have a bad reputation, it’s all political. They’re actually a great snack! http://www.webmd.boots.com/healthy-eating/guide/good-eggs. To make egg mayo hard boil eggs (how to), let them cool slightly, peel and then add one teaspoon of mayonnaise per egg. Mash thoroughly with a fork.
Cheddar: a low glycaemic index food which is a good source of calcium and proteins; something to keep you going. Check out the facts here: http://nutritiondata.self.com/facts/dairy-and-egg-products/8/2
