Tomato passata is like tomato paste in case you were wondering, and that's what I used. These came out so delicious and my guests and I enjoyed them very much! The spices were right on for us and I wouldn't change a thing next time I make them!
I didn't have a clue what tomato passata was, so I substituted 1 can Rotel tomatoes with green chilies instead, then used only 3 whole chilies instead of 5. The kick from the tomatoes was an added bonus in the final product! They were delicious Marie! I can see why your family likes them so much. Now I know what I can use for my leftover turkey during the holidays. It's always great to have new recipes for leftovers! I did use whole wheat flour tortillas, as we like them better than the corn. These will be enjoyed at my house for years to come!
