Cut the cauliflower into florets.
Place the cauliflower florets into a bowl with the water and cover with plastic wrap.
Pop the bowl into the microwave to cook on high for 8 – 10 minutes. Until the cauliflower is tender.
Remove the plastic wrap and drain the water. Be careful as everything will be hot. Then drizzle the cauliflower with the olive oil, lemon juice, and salt and pepper and toss it to coat it all over.
