This is a nice side dish, served warm or cold, or you could mix it with some smaller shaped pastas for something a little more filling.
1 cup shelled and steamed edamame
1/2 cup mini tomatoes, sliced in half
2 tablespoons Parmesan cheese, shredded
2 scallions, roughly chopped
1 tablespoon olive oil
1/2 tablespoon balsamic vinegar (optional)
Combine and toss together. Serve immediately, or chill for 15-30 minutes.
