Drain the spinach. Do this by wringing it out with clean hands and putting it in a dish towel and squeezing out the water.
Add the spinach to a small bowl. Add remaining ingredients and stir until combined.
Transfer to a bowl you would like to serve the dip in. Cover in plastic wrap.
Chill for at least 2 hours before serving.
Serve with sliced bread, crackers or vegetables.
