I start by washing and chopping all my vegetables, grating the cheese, and seasoning the beef. Having everything ready makes cooking much faster and prevents burning the meat.
In a skillet over medium heat, I add the ground beef, onions, bell peppers, garlic, and jalapeños. I cook everything until the beef is browned and the vegetables are soft. Season with cumin, smoked paprika, salt, and pepper.
Once the beef is fully cooked, I sprinkle the cheddar and Monterey Jack over the meat. I cover the skillet for a few minutes so the cheese melts perfectly into the beef mixture.
I slice the rolls and layer in the cheesy beef mixture, lettuce, tomato slices, and pickled jalapeños. Then I press the sandwich slightly so all the flavors meld together.
This sandwich tastes best hot, right out of the skillet. I like to serve it with a side of chips or a simple salad for balance.
