The minors beef stock has amazing flavor, if you don't have any you can also just use better than bouillon (not as good).
Injection marinade:
4 cups water (bring to a boil and then add the rest of the ingredients, simmer for 15 minutes)
2 T Minors beef stock
1 T Minors Au Jus
1 t. Cholula Chipotle Hot Sauce
