So simple it almost seems silly to post it. This is a great summer side dish or salad when the veggies are at their peak. This is just a suggestion of veggies to use add more to the list (as I do) or change it as the harvest changes. Its very important to use a very good, flavorful oil here. I got this from about.com and they never gave how many servings so I am guessing. I usually make a big batch of this and keep it in the fridge to use for a few days. The leftovers are always great tossed with pasta or risotto. The cook time is the chill time. We sometimes add a drizzle of vinegar at the table and/or a handful of grated cheese if it strikes our fancy.
