I just made this off the top of my head the other night and I didn't measure so I just guessed on the measurements here, but I’m sure they're close. It sounds and tastes pretty simple but it turned out really good. My brother actually complimented me on it which never happens (and I’m pretty experienced in the culinary field so it was saying something).
Boil a large pot of salted water. Add pasta and cook until tender.
Coat the bottom of a medium nonstick skillet with olive oil and add butter. Heat to medium-high heat. Add scallions and cook for about four minutes (should be slightly brown) then add tomatoes. Cook for another two minutes then add the wine and reduce.
When pasta is done drain and toss with olive oil to coat (about 2 T.). add scallion sauce and seasoning to pasta and toss.
