Use a round cutter to cut the flour tortilla into smaller versions.
If you would like to shape and crisp up the tortillas, brush them with water, and place them over your oven rack and bake for 5 to 10 minutes. Let them cool down.
Combine the ingredients for the salsa, add 1 tbsp olive oil, lemon juice and season to taste with pepper and salt.
Chop the cooked prawns and add to the salsa.
Divide the salsa mix between the tortillas, add a touch of sour cream and garnish with some fresh coriander.
