Preheat the oven to 350
Prepare 3 lbs of pounded chicken. Brining it ahead of time is recommended.
Mix the taco mix, tomatoes, chilies, and chicken BTB in the mixing bowl
Pour half of the taco/veggie mix into the bottom of the baking pan
Spread the chicken above the taco/veggie mix
Pour the rest of the taco/veggie mix over the chicken
Place in the oven & bake until 165 F, usually 30-45 mins, maybe 60
Remove from oven and let rest for 10 mins or so
Use the potato masher to press the chicken apart
If desired, remove the chicken from the taco/veggie mix and chop it with the knife
Mix the shredded/chopped chicken back into the taco/veggie mix and bake another 5-10 mins so the chicken absorbs more of the flavor
