Cook the pasta in a large pot of boiling salted water until al dente, following the package instructions.
Preheat your oven to 350°F (175°C). Meanwhile, place the skillet over medium heat and add the ground beef.
Drain any excess fat from the skillet and stir in the taco seasoning. Add the salsa, black beans, and corn; stir well to combine.
Mix the cooked pasta with the beef mixture in a large bowl. Add 1 cup of cheese and mix until incorporated.
Transfer the mixture into your baking dish and spread it evenly. Sprinkle the remaining cheese over the top.
Place in the oven and bake for 20 minutes, or until the cheese is melted and bubbly.
Remove from the oven and allow it to cool for a few minutes. Before serving, top with halved cherry tomatoes, a dollop of sour cream, and freshly chopped cilantro for added freshness.
