Preheat the oven to 150 C. Line an 8-inch loaf pan with parchment paper.
In a food processor, add the almonds, cashews, pumpkin seeds, rolled oats, ground cinnamon, and salt. Roughly chop them, then transfer the mixture into a bowl.
Add the water and the pitted dates to the same food processor. Blend until the dates turn into an almost paste-like consistency. Stop and scrape down the sides as needed.
Add the nut-seed-mixture. Continue to process to combine all together.
Transfer the mixture into the lined loaf pan. Press it down firmly.
Use a knife to slightly cut out the lines between each bar. Bake at 150 C / 300 F for 25 minutes first, then turn down the oven to 125 C / 250 F for another 5-10 minutes until they're golden brown.
Transfer to a wire rack to cool down completely. Then cut into the lines to separate each bar. EAT!
