In a food processor, combine all the dry ingredients and pulse to mix. Add the egg and water and pulse again until combined and the dough forms a ball.
Dump the dough out onto a piece of parchment paper. Place another piece of parchment over the top. Roll the dough out to 1/8" thick. Cut out desired crackers with a cookie cutter or pizza wheel and place on a parchment paper covered baking sheet.
Brush the tops with olive oil and sprinkle with your favorite seasoning.
Bake for 10-12 minutes until lightly golden brown. Cool before serving. Store for a few days in a sealed container or plastic bag.
