King prawns from the barbecue recipe

Ingredients:
1/2 bag unpeeled king prawns (possibly frozen), 5 tbsp olive oil, 2 tsp Vis-a-vis, black pepper, salt, 2 stalks spring onion (finely chopped into rings) red pepper (finely chopped into rings), skewers (optional)
Preparation method:
Defrost the frozen prawns by placing the bag in the refrigerator overnight. You can also defrost the prawns by placing them in a bowl of cold water until they are soft. Take a bowl and put the olive oil and Vis-a-vis in it. Season with some black pepper and salt. Mix the prawns in it and let it marinate in the refrigerator for at least 1 hour. Just before the start of the barbecue, thread the prawns onto the skewers (optional). Place them on the barbecue and turn them over once. The prawns are ready when they turn pink; this is after about 4 to 5 minutes. Place the prawns on a plate and finish with the spring onion and the finely chopped red pepper. Serve with lime or lemon wedges.
