Wash the chicken breast, pat dry and cut into cubes, then fry in a little olive oil. Add the onions, bell peppers and the carrots. Fry everything for about 10 minutes.
Put the spaghetti in boiling salted water. Let it steep a little shorter than recommended so that it is still firm to the bite. Now add the spaghetti to the chicken and vegetables. Let fry briefly while stirring. Season with sambal olek, salt and paprika powder. Take the pan off the heat and only now fold in the sour cream.
