1. Combine seeds with olive oil and salt and mix together thoroughly. Toast at 350 degrees until slightly brown.
2. Combine seeds, dates and water in a food processor and puree until mixture starts to stick together. Add a little more water if necessary to help mixture come together.
3. Pick up mixture and squeeze it together. Flatten on a cutting board or sheet of wax paper to form into one even rectangle shape using the edge of a knife to make the edges straight.
4. Slice into 8 equal squares. For best results store in the fridge, although bars can be kept at room temperature.
