Cut the ciabatta roll in half. Drizzle olive oil onto the cut side of each half and put under a hot grill until toasted. Crack on with the other steps until it's ready but keep an eye not to burn it. When ready, leave to one side.
Add the butter to a frying pan over a medium-high heat
Add the minced garlic
Add the king prawns
When the king prawns begin to change (this will happen quite quickly) - add the white wine and reduce by half. Give the frying pan a shake to move the the prawns and coat them.
Once the wine has reduced, add the romesco sauce and reduce the heat. Don't forget to give it a good stir and coat those beautiful prawns. You're not looking to cook the romesco really, just heat it up!
Once the prawns are cooked through, remove from the heat
In a wide rimmed bowl, add the ciabatta. Place the garlic king prawns on top and spoon over the top some of the romesco sauce. Drizzle some around the bowl as well. Looks nice and you'll want to mop it all up. Garnish with flatleaf parsley and your done!
