Begin by gathering all the ingredients.
Next, take the beef and cut it into 1-inch pieces, seasoning it with salt and pepper.
Now, take a large skillet and add 1 to 2 tablespoons of oil to it. Heat the oil and add the beef to it. Sauté it until the meat is just browned. Make sure to cook it over high heat.
Throw in the garlic and add soy sauce and Worcestershire sauce and allow all the ingredients to cook for about 2 to 3 minutes more, or until you attain the preferred doneness.
Take the skillet off the heat. Add more salt and pepper to taste.
The next step is to split the sandwich rolls lengthwise. Once that’s done, it’s time to assemble the dish.
Begin by placing the shredded lettuce and tomato in the rolls first.
Divide the meat among the four rolls, adding it on top of the lettuce. Add a little bit of guasacaca and any other preferred sauce. Top the sandwich off with some potato sticks and there you have it. Your Pepito is ready to be served!
