Cook the pasta in 1/2 l water with broth for about 10 minutes until al dente. Pour off, catching the broth
Wash the basil and chop finely, except for a little to garnish. Peel and chop garlic if necessary. Mix with 5-6 tablespoons of broth, vinegar, salt, pepper and sugar. Whip the oil into it. Mix marinade with basil and noodles. Let it cool down
Peel onion and cut into half rings. Wash and halve the tomatoes. Clean and wash the lettuce and pluck into bite-sized pieces. Mix everything with the noodles and season again. Garnish with remaining basil
The pasta salad tastes even spicier if you add 1 teaspoon of mustard to the salad dressing. If you add the onion rings to the noodles 2 minutes before the end of the cooking time, they are more digestible
