Preheat a large pan over medium-high heat.
Add the olive oil, half the shrimp and dust with salt and pepper. After two minutes, flip them.
Remove them from the pan, and repeat the previous step with the rest of the shrimp. Remove them from the pan and reserve.
Once they have cooled down, chop half of the shrimp into medium pieces.
Mix all of the shrimp with the ingredients for the filling. Taste and adjust the level of salt and pepper.
