In a large stock pot, add pasta, peppers, corn, red onion, taco seasoning, RO*TEL, olive oil, and red pepper flakes. Stir to combine, cover, and turn heat on high. Once boiling, reduce heat to medium/low (so it's simmering), stir, and cover. Cook for 12-16 minutes or until pasta is tender and most of the liquid is absorbed - stir throughout this cook time.
Add black beans, lime juice, and cheese; stir well to combine.
Top with green onions. Serve immediately and enjoy!
