Bring a large pot of generously salted water to a boil.
When the water comes to a boil add the corn and cook for 3 or 4 minutes . Remove and set aside.
Add the pasta to the water and cook to your desired doneness. I like my pasta cooked for more time than al dente, so that is your personal choice.
Trim the corn off the cob and slice the tomatoes in half. -While the pasta is cooking heat a large skillet and add a little olive oil to the pan.
Add the garlic and red pepper flakes. Cook on medium until the garlic becomes aromatic. Add the tomatoes and cook until they have released their juices, about 5 minutes. Add the red pepper and combine. Add the corn that you trimmed from the cob and toss to combine.
With tongs add the cooked pasta to the cooked vegetables adding additional pasta water to create a sauce. Add the cotija cheese and combine, heating through so that it becomes part of your sauce.
Remove the pasta from the heat, top with the green onions and additional cheese for serving!
