How to cook
Boil the orzo according to package directions in salted water. Strain it in a strainer.
Cut the crab rolls into round circles. Thaw the mussels if they've been frozen.
Put the boiled orzo, crab rolls, mussels and the olives, cut into slices, in a bowl.
Pour the resulting sauce in the bowl with the other ingredients and stir well. Optionally, decorate with any ingredients you have available.
