Yummy- this was really good. My family loved this. I had a half a bag of Tostitos so I used those. I crushed them up instead of taco shells. I also didn't add the onion as I didn't notice it until I was finished cooking. I used Homemade Taco Seasoning Packet Replacement for the taco seasoning. My family really enjoyed this. We thought the can of diced tomatoes was a bit much, I would just use a bit less next time. We will be making more often.
This is casserole is a real family pleaser. I have made something very similar to this for many years. It's a frugal recipe that combines all of the broken cruncy tacos and the last tortilla chips from the bag with on-hand pantry and fridge ingredients to make a great meal! It is nicely seasoned as is but my husband likes me to use Ro Tel diced tomatoes and chilis in place of the plain diced tomatoes for extra zip. We like it served on a bed of shredded lettuce and garnished with sour cream. Delicioso! I have put it together in the morning, refrigerated it and baked it after work at 350F for 30-40 minutes for a make-ahead meal. Thanks Shannon.
