Cafe Rio Pork Barbacoa

5 - 6 pounds pork tenderloin (or roast)
21 ounces Dr. Pepper
1 cup brown sugar
3/4 cup white sugar
2 cloves garlic
1 (7 ounce) can chipotle chilies in adobo sauce
6 ounces medium red taco sauce
1 teaspoon dry mustard
1 teaspoon cumin
1/2 teaspoon salt
1/2 teaspoon pepper

Place pork in the crock pot and make sauce.

Here's the trick with the sauce: Remove chipotle chilies from the can and put in the measuring cup that you'll measure your Dr. Pepper with. Pour Dr. Pepper over them and remove the chilies (and throw away) just to get the sauce off and then continue pouring Dr. Pepper into the measuring cup until you reach the full 21 ounces. You'll also need to rinse out the chipotle can with the Dr. Pepper to get all the adobo sauce out. Do NOT use the chipotle peppers (I did this and it was killer hot). You can add 1 or 2 for a kick if you want.

Blend all ingredients together in either a blender or with an immersion blender until combined and pour over the pork. Cook on high for 5 hours or on low for 8 hours until the pork is easily shreddable. If you've never had a Cafe Rio Pork Salad, what you'll want to do to make this is take a flour tortilla and melt some cheese on it. From there, here's the layers:

White Rice (I'll post my recipe later for Cilantro Lime Rice)
Black Beans (I just used canned that I heat up on the stove and add seasoned salt and pepper with some garlic powder)
Romaine Lettuce, chopped
Pico de Gallo
Guacamole
Cilantro Ranch Tomatillo Dressing
