Cook the bacon in a skillet over medium heat without adding oil. The bacon will release its own fat. Once cooked, break it into small pieces by hand—it’s easier than using a knife.

Save the bacon fat in the skillet and use it to cook the quartered onion, half a tomato, and the chopped nopales. Season with finely chopped garlic or garlic powder, plus salt, black pepper, and vegetable seasoning to taste. Cook over high heat for about 8 minutes.

When the mixture darkens in color, add the chopped cilantro and mozzarella cheese.
