Q. I cooked pasta in a clean meat (Kosher) pot. Can I add cheese to that pasta once it’s on a plate? 

 A. No, you can’t add cheese directly to the pasta, because it absorbed some “indirect-flavor” from being cooked in a meat pot, even though it was a clean pot with no meat in it at the time when you cooked the pasta. But you can eat that pareve pasta in the same meal as cheese, because it’s not enough flavor to actually make that pasta dish considered meat. You don’t have to wait any separation time after eating the pasta.
