I used
1/2 of a pork loin roast
1 pgk taco seasoning - mine is low sodium
1 can cream of chicken soup
1 cup salsa
I added an onion and some garlic powder - neither was in the recipe. I probably added some Ortega taco sauce, too.
Cook 4 or 5 hours in the crockpot. The recipe called for a can of refried beans added at this point, but I didn't bother. You can serve it just as meat dish, or a sandwich filling for buns or tortillas.
