Gather and prepare your ingredients. Line a 2lb loaf tin with parchment paper, or lightly grease with olive oil. Preheat your oven to 190°C/170°C fan.
Place the chia seeds, psyllium husk, oats, nuts, seeds, and salt into a large bowl. Stir to combine.
Pour in the water and olive oil and mix well.
Scrape the mixture into your prepared tin. If you like, you can leave it to soak for 30 minutes - 8 hours at this stage.
Bake for 60 minutes. Remove from the tin and bake for a further 15 minutes. Remove from the oven and allow to cool completely before slicing.
