Start cooking your pasta.
While the pasta is cooking, chop up your tomatoes (I used regular tomatoes. But I usually make it with cherry tomatoes) garlic, basil and green onions (the white part only)
In a bowl, mix your olive oil, balsamic, garlic and salt and pepper
Whisk it all together
When your pasta is done, drain and rinse under cold water until pasta cools. (This is a cold dish)
Add your pasta to the bowl, mix, add your tomatoes, basil and green onions, mix.
And it's simple as that! I found this recipe on vegweb and tweaked it slightly. It's one of my favorite dishes, I've taken it on camping trips, even had it for breakfast once. Yeah, it's that good.
