Grill the following vegetables, I brush them with a little olive oil and balsamic:
Chop up tomatoes and fresh basil.
Cook your favorite pasta and run cold water over it, this is a cold pasta salad.
Make a balsamic dressing or use store bought.
I used balsamic vinegar, a little olive oil, garlic, shallots, Dijon mustard, chopped basil, salt, and pepper. Whisk everything together to your taste. Sorry I didn't measure.
In a big bowl add the pasta, veggies, and basil. Stir. Pour dressing over pasta and veggies. Stir and add more until the pasta is well coated. Add in feta cheese. Serve cold. Will keep for a couple of days.
