What do you do with leftover taco fixings (aside from have tacos again)? My answer, to make a casserole.
As Lydia said in her post yesterday, we had tacos for the fourth of July and with it, lots of leftovers (no guac though). I didn't want to have the same dinner over, so I mixed everything together in a large bowl - this included seasoned taco meat, refried black beans, Spanish rice, tomatoes, onions, salsa, sour cream, and crunchy taco shells (broken into bite sized pieces). I then put the mix in a casserole dish and covered it with leftover cheese (I added a bit more cheese too) and cooked it at 375 degrees for 30 minutes.
I still had shredded lettuce and 1/2 an avocado, so that became a salad. I added some carrot shreds and hot peppers and Mom made a vinaigrette for it and we squeezed a fresh lemon over it all. The salad went nicely with the casserole and gave us something fresh to eat.
When I served the dish, we ate it with leftover tortilla chips, salsa and sour cream (some of Lydia's guacamole would have been delicious too). It was a really good use of taco leftovers and I would make it again! The best part is you can add anything you like to the dish and it will probably work well!
