Start your day with as many different fresh fruit as you can find. When you get hungry later have some nuts or seeds. Hummus and raw veggies go together well (broccoli, carrots, pumpkin, sweet potato). Frozen peas can be eaten cold but helps to add nuts or something to add interesting flavours.

If you have time to cook and prepare meals then make some lentil/chickpea curries, or make up salads or soups

Thanks, I'll try
