In large frying pan, heat the oil over medium heat. Add the ground beef and cook until browned, about 3 minutes. Stir in the chili powder, salt and pepper. Add the salsa and simmer over low heat to combine, about 10 minutes. Cook pasta to al dente, drain it and toss it with the sauce, lime juice, cilantro and 1 cup of cheese. Stir until cheese is melted. Sprinkle with remaining cheese and serve with lime wedges if you like.
