I changed the recipe to what I had in my cabinet and it still tastes delicious. I didn't have chives or plum tomatoes. I used fresh oregano and fresh basil,and used crushed tomato sauce instead of plum tomatoes. I chopped up the artichokes and my family (picky eaters)never knew they ate artichokes. I served the sauce over a bed of whole wheat pasta and baked chicken breasts seasoned with garlic powder and Adobo.
