In a large bowl, whisk together the flour, salt, and yeast. Toss in the cubed cheese so the cubes are coated in the flour. Slowly mix in the warm water using a wooden spoon or rubber spatula. Mix until just combined. The dough will be very sticky and shaggy looking. Cover the bowl with a kitchen towel and let rest for 12-16 hours in a warm, dry place (I keep it on my kitchen counter).
