Divide the cauliflower into small bouquets.
Mix it with the shrimp, spinach, red onion, olive oil and vinegar.
Season with the ginger, salt and pepper.
Cut the bread into slices and lay them on a baking dish.
Drizzle the olive oil over the slices and salt to taste.
Toast in the oven at 400 degrees F (200C) until they become golden brown — about five to seven minutes.
Serve with the salad.
