Creating these incredible oven baked tacos involves these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Arrange taco shells in a baking dish.
2. Cook the Meat: In a large skillet, cook the ground meat over medium heat until browned. Drain excess fat if necessary.
3. Add Vegetables: Stir in the chopped onion, bell pepper, and jalapeños. Cook until the vegetables soften, about 3-5 minutes.
4. Season the Filling: Add the taco seasoning, black beans, corn, and salsa to the meat mixture. Stir well to combine. Cook for another 2-3 minutes until everything is heated through.
5. Fill Taco Shells: Spoon the filling into each taco shell generously. Arrange the filled shells upright in the baking dish.
6. Top with Cheese: Sprinkle shredded cheese over the filled taco shells.
7. Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes or until the cheese is melted and bubbly.
8. Serve Immediately: Remove from the oven and let cool slightly. Top with shredded lettuce, diced tomatoes, and any other desired toppings.
9. Add Sour Cream: Serve with a dollop of sour cream and sprinkle with fresh cilantro if desired.
