Cut the avocado lengthways, remove the stone and scrape out the flesh with a spoon and mash it. Squeeze the lemon or lime. Drizzle the avocado with lemon juice. Chop the chilli pepper into small pieces. Peel and chop the onion.
Fry the thawed prawns or shrimps in a little oil, allow to cool and cut into small pieces. Mix the cream cheese, onion, chilli pepper and shrimp pieces with the mashed avocado. Season the mixture with salt and pepper.
Pour into four coffee cups and turn out onto plates. White bread and salad go well with it!
