I found this fascinating quote today:
- Heat a large skillet over medium heat, and pan-fry the round steaks 5 minutes on each side, or to desired doneness.
- Slice the rolls lengthwise. Spread about 1 tablespoon of sour cream onto one side of each roll, and top with about 1/3 cup of mashed pinto beans per sandwich. Place a cooked round steak per sandwich on top of the pinto beans, and then layer each sandwich with one-fourth of the avocado slices, tomato slices, and sliced pickled jalapenos, about 1/2 cup of shredded lettuce, 1/4 cup of cilantro, and 1/4 cup of crumbled queso fresco cheese. Squeeze a lime wedge over each sandwich, close, and serve.
