Bring a small saucepan of salted water to the boil.
Pull the tips and spines off the snow peas and blanche them in the boiling water until vibrant and immediately plunge them into ice water.
Saute the chorizo slices in a pan on high heat until nicely browned, remove, allow to drain and cool.
Peel the cucumber and to seed it, cut it in half lengthwise and then run a small teaspoon down the length, removing the seeds as you go, then slice the cucumber halves the same size as the chorizo.
Once the snow peas and chorizo have cooled toss the spinach, chorizo, snow peas, olives, cucumber and half of the crumbled feta into a large mixing bowl, season and toss with a little oil and vinegar.
Present on the serving plates and top with the remaining feta.
