Purée apricots in a food processor with 150ml boiling water and the oats, then scrape the mixture into a bowl. Toast coconut, sunflower seeds and sesame seeds in a non-stick pan over a low heat, then stir into the apricots with the cranberries, hemp powder and chia seeds to make a thick paste.
Roll into a long log on a sheet of cling film. Wrap tightly, chill, then slice thinly to serve. Will keep in the fridge for 2 weeks.
