Mix all ingredients together in a medium bowl. Allow the mixture to sit while you prepare the beans.
Coat the bottom of a medium skillet with oil and place it over medium heat.
When the oil is hot, add the onion. Sauté until soft and translucent, about 5 minutes.
Add the garlic and sauté for about 1 minute more, until very soft.
Stir in the cumin, oregano, beans and beer.
Raise the heat and bring the liquid to a boil. Lower the heat and allow it to simmer for 10 minutes, stirring occasionally. Add water if the pan becomes too dry.
Mash about half of the beans with a potato masher or fork.
Taste-test to see if all of the alcohol has cooked off. If not, continue simmering, adding a bit of water if needed, until you can't taste the alcohol anymore.
Remove from heat and stir in the lime juice. Season with salt and pepper to taste.
Stuff the shells with refried beans and top with slaw and/or any other toppings you like. Serve.
