Next, add eggplant, squash, snow peas and other veggies to the plastic bag. Seal and shake the bag to cover all of the vegetables; refrigerate for 2 hours, shake the bag after 1 hour to make sure all veggies are covered with marinade.
Drain the veggies from the Ziploc bag in a colander, don't save marinade. Place vegetables in a grill basket or disposable foil grilling tray.
