Mix cassava flour and salt in a small mixing bowl.
Add water and olive oil into cassava flour mix and mix throughly.
When liquid and dry ingredients are mix, begin to mold the dough into a ball. If it doesn't stick together well, add a little more water (1 tbs at a time). You don't want it too wet, but too dry is also a problem!
Take ⅓ of the dough and place it on a large sheet of parchment paper, and place another large sheet above it.
Roll the dough out until it is thin (1/8"). Remove top parchment paper.
Score dough into squares with a knife, cutting equal strips down, and then squares across.
Slide parchment paper with dough on top onto a baking sheet. Bake in the oven at 375 for 15-20 minutes, or until edges begin to be a golden brown then remove and cool.
Repeat for remaining dough. Makes about 50-100 small crackers.
