Cafe Rio Pork Recipe

So I LOVE cafe rio's sweet pork barbacoa. I searched the net and found this recipe for it. Josh and I tried it out and it is SO good! We made some lime cilantro rice (it's just 3 cups of cooked rice combined with 1/2 tsp salt, zest of 1 lime, juice of 2 limes, and 1/2 c. cilantro) and put both on corn tortillas. Yum!

3-4 lbs pork roast or pork loin
1/4 teaspoon oregano
1/4 teaspoon cumin
1/2 teaspoon salt
1/2 onion
2 garlic cloves
water, to cover
Sauce
1 (14 ounce) can enchilada sauce
3/4 cup Coca-Cola or Dr. Pepper cola
1 cup brown sugar
Directions
1)Cut pork in large chunks. Put in large crock pot and add water just to cover. Add seasonings. Cut onion in 4 large pieces, crush garlic and add to water. Cook pork on low all day or on high for 3 to 4 hours, or until tender and pork pulls apart easily. Drain water and remove onions and garlic. Pull pork and return to crock pot.
2)In a separate container mix enchilada sauce, soda and sugar. Add to pork in the crock pot. Cook 1 hour longer.
