Place a steamer insert into a large saucepan and pour in water to just below the bottom of the steamer.
Turn the heat to medium high and bring the water to a boil.
Bring down the heat to medium low to simmer, then add cauliflower florets, cover, and steam until tender, about 10 minutes.
Remove the cauliflower from the pot and transfer to a food processor. Blend until smooth.
Add cassava flour, coconut flour, egg, and sea salt, and pulse until combined and forms a dough.
Place the dough in the refrigerator for 15 minutes.
If dough is too sticky, add cassava flour 1 tbsp at a time while kneading until it reaches the right consistency.
Sprinkle some cassava flour on a large cutting board or a clean countertop.
Roll your dough into ropes about ½ to ¾ inch thick, then cut the ropes into pieces that are about 1 inch long. If you'd like, use a fork to create indents on the gnocchi.
Store half of the gnocchi in an airtight container in the refrigerator or the freezer, and save it for lagter. Use the other half for the this recipe.
