You can use salsa instead of the fire roasted tomatoes - I would recommend 1 1⁄2 cups of salsa. The juices in the tomatoes (or the salsa) provides the necessary moisture for the dish. Since we’re layering with corn tortillas, the filling needs that moisture.
If desired, you can substitute ground turkey for the ground beef. You can even use shredded beef, chicken, or pork if that your tastes better.
Frozen or canned corn can be added to the meat mixture in the skillet if desired.
