1 pound cooked and cooled pasta, such as penne, bowties, etc.
1 pint grape tomatoes, cut in half
3 cloves of garlic, minced
1/2 red onion, diced
4 ounces of feta cheese, crumbled (low fat varieties are fine)
2 - 3 tbsp. fresh dill, minced
1/2 tsp. salt
1/2 tsp. fresh cracked black pepper
1/2 cup extra virgin olive oil
1/4 cup red wine or champagne vinegar
2 zucchini and/or summer squash, cut into bite-sized cubes.

Mix together, chill for a few hours, or overnight, and allow to warm up slightly before serving so the flavors come alive.
