Sauce verte

Green sauce or greensauce is a family of cold, uncooked sauces based on chopped herbs, including the Spanish and Italian salsa verde, the French sauce verte, the German grüne Soße or Frankfurter grie Soß , the British mint sauce and greensauce, and the Argentinian chimichurri.: 354  The Mexican salsa verde, though also called a "green sauce", is instead based on tomatillos and is commonly cooked; the New Mexico version uses a green chile base. Green sauce has a long history in many parts of Europe. It was certainly present in the Middle Ages, and may date to the Classical period.: 354
