Put the cauliflower in a food processor and pulse until you have a fine grain, but not liquified (it should look similar to couscous or rice.) Measure out approximately 2 cups and transfer to a microwave-safe bowl. Cook for about 1 minute, remove and stir. Cook for 2 minutes. Let the cauliflower cool slightly.
When cool, line a fine-mesh strainer with cheesecloth and put the strainer over a bowl. Using a spoon or spatula, press as much of the water as you can out of the cauliflower.
Transfer to a large bowl and mix in the eggs, green onions, and salt. Mix well until you have a batter.
Line a baking sheet with parchment paper. Spread the batter into 6 circles, spreading as thin as possible.
Bake for 8 minutes, flip and bake for 8 more. Before serving, you can heat gently in a nonstick skillet to warm and soften if necessary.
