In a large frying pan, heat the oil over medium-high heat.
Once hot, add the bacon and let it cook until crispy. Remove the crispy bacon from the pan and transfer it to a plate lined with absorbent towels to absorb any excess fat.
Next, in the same frying pan, cook the chorizo for about 5-6 minutes. Remove and place it on the plate with the bacon.
Now, add the pork meat and cook for approximately 7 minutes. Don't worry if it doesn't appear fully cooked at this point; it will continue cooking with the remaining ingredients.
Add the beef to the frying pan and cook for 8 minutes. Remove and set it aside with the other cooked ingredients.
Now, it's time to incorporate the onion, serrano chili, and green pepper into the pan. Allow them to cook for approximately 3 minutes. Then, add the cooked meat, tomatoes, and sausages, and let them cook for around 10 minutes. You'll notice that the tomatoes will start releasing their juices during this time.
Next, pour the beer, season with salt and pepper, and cover. Keep cooking for another 5 minutes until all the meats are soft and well cooked.
Just before serving, stir in the chopped cilantro.
Enjoy your Discada! Serve it with sides like creamy guacamole, pinto beans, and a stack of warm flour tortillas.
