Nuts and seeds: great source of protein, fibre and healthy fats. Macadamia, walnuts and pumpkin seeds (do not touch if you have nut allergies). You can do a dry roast in a frying pan until golden brown, which will add more flavour.
Fresh fruits: firm green/yellow bananas if you do not react to them, grapes, blueberries, apples, pears, papayas and mangos.
Rice crackers or rice cakes: they are light and portable and perfect for on the go! Top then with nut butter and honey or cheese slices for a protein hit (tussers or mozzarella, ricotta, Kiri or Philadelphia (mild cream cheeses).
Hard boiled eggs: eggs are a great source of protein and can be boiled ahead of time for an easy on the go snack. Just keep them cool in a cooler bag.
Beef biltong: a great source of protein while on the go (must be plain biltong, no chilli bites or droewors as it contains dried spices with gluten).
Cheese sticks: easy to munch on whilst on the go and a great source of protein and calcium (tussers or mozzarella).
Carrot, cucumber, and celery sticks: great source of fibre while on the go.
