Preheat Oven: Preheat your oven to 375°F (190°C). Grease a loaf pan or line it with parchment paper for easy cleanup.
Mix Ingredients: In a large mixing bowl, combine the ground beef, breadcrumbs, salsa, corn, black beans, diced onions, diced jalapeños (if using), taco seasoning mix, and beaten egg. Mix until all ingredients are well combined.
Form Meatloaf: Transfer the meatloaf mixture into the prepared loaf pan, pressing it down gently to form an even layer.
Add Topping: Spread an additional layer of salsa over the top of the meatloaf, ensuring it is evenly coated. This will add moisture and flavor to the meatloaf as it bakes.
Bake: Bake the meatloaf in the preheated oven for 45-50 minutes, or until the internal temperature reaches 160°F (71°C) and the top is golden brown.
Add Cheese: Remove the meatloaf from the oven and sprinkle the shredded cheese over the top. Return it to the oven and bake for an additional 5 minutes, or until the cheese is melted and bubbly.
Rest and Serve: Once cooked, allow the meatloaf to rest for a few minutes before slicing. Garnish with fresh cilantro, if desired, before serving.
Notes:

For a spicier meatloaf, use hot salsa and include the diced jalapeños.
Serve with a side of Mexican rice or a simple green salad to complete the meal.
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving.
