Remove the outer leaves from the lemon grass. Chop the inside very finely. Simmer half with 1/8 l water and stock for about 5 minutes. Season with vinegar, 1 pinch of chilli and 1 pinch of sugar.
Peel and chop the garlic. Remove seeds from chillies, wash and cut into rings. Onions clean, wash, cut into rings. Cut pineapple into pieces, if necessary clean and peel before and remove the stalk.
Divide lettuce into leaves, wash and spin dry.
Heat the oil in a pan. Fry the minced meat in it until crumbly. Fry the garlic, chilli and the rest of the lemongrass. Season with salt and pepper. Sieve the marinade and pour on. Fold in onions.
Wash the parsley and chop finely. Chop the nuts coarsely. Mix both with pineapple and chopped nuts. Fold in lettuce. Thin flat bread tastes good with it.
