Cook the spaghetti. Cut the garlic into small pieces. Remove the kernels from the peppers and cut into thin slices. If you like it spicy, you can also use red peppers. Dice the feta cheese. Wash the cucumber well and grate finely.
Make the bag of salad dressing only with oil (not water) and add 1.5 teaspoons of broth. Now mix all ingredients except for the feta cheese and only add the feta cheese at the end.
