Prepare the Torta Filling:

1. Marinate the Meat:

   • In a small bowl, combine olive oil, cumin, chili powder, garlic powder, salt, pepper, and lime juice. Rub this mixture onto the carne asada (or your chosen protein) and let it marinate for at least 15 minutes.

2. Cook the Meat:

   • Heat a grill or grill pan over medium-high heat. Grill the carne asada slices for about 3-4 minutes per side, or until fully cooked and slightly charred. Once cooked, remove from heat and let it rest for a couple of minutes before slicing into strips.

Assemble the Torta:

1. Prepare the Rolls:

   • Slice each bolillo roll in half, but not all the way through, leaving a hinge. You can lightly toast the rolls in a skillet or oven if desired for extra crispiness.

2. Spread the Condiments:

   • In a small bowl, mix together the mayonnaise, sour cream, salsa verde, cilantro, and hot sauce (if using). Spread a generous amount of this mixture on both sides of each bolillo roll.

3. Layer the Torta Ingredients:

   • On the bottom half of each roll, spread a layer of refried beans (if using). Add the grilled carne asada slices, followed by onion slices, tomato slices, avocado, and jalapeños.

4. Assemble and Serve:

   • Place the top half of the bolillo roll on top to complete the sandwich. Press down slightly to hold everything together. Slice in half and serve immediately.
