    WOW, this was absolutely delicious! I had to size down the vegetables & broth a tad for my 4 qt. crockpot (we are a family of 2) but I kept the tomatoes and spices the same. Not having a leek on hand, I substituted a sweet onion. And since it was a main course for us, I added a pound of Italian seasoned ground turkey. Oh my, the taste was absolutely perfect! This is a definite keeper for us! Thank you for the great recipe!!
