To make the base dough:

1. Preheat oven to 375 degrees Fahrenheit
2. Blend hearts of palm, eggs, olive oil, and water in a blender until smooth. 
3. Pour into a mixing bowl.
4. Add the almond flour, coconut flour, psyllium powder, hemp seeds, baking powder, and salt. 
5. Mix on low to medium for about 2 minutes, or until a stiff dough is formed. 
6. Divide the dough into 3 equal balls.  

To make the crackers:

1. Roll each ball into a log about 12 inches long and 1 inch around.  
2. Form each log into desired shape using hands and a flat surface if necessary.
3. Combine the ingredients to create the three separate seasonings. 
4. Sprinkle one of the seasoning mixes onto a cutting board and roll/press one of the logs into it until fully coated. Move to a parchment lined baking sheet.  
5. Clean any extra seasoning off the cutting board and repeat with another seasoning mix and log. 
6. Repeat with the third seasoning and log.  
7. Bake the logs in the oven for 25 minutes. 
8. Remove and cool for 30 minutes for easier slicing. 
9. Once cooled, slice your crackers into your desired thickness. 
10. Place the slices on a parchment-lined cooking sheet and sprinkle with additional salt if desired. 
11. Reduce heat to 350, and bake the crackers for 25 minutes, or until golden brown and crisp. 
12. Cool completely at room temperature before storing, or they will become soggy.
