Combine all prepared vegetables in a bowl.  To make vinagrette, mix the oil (in any combination to make 3/4 C), red wine vinegar, garlic, salt and pepper in a jar and shake to mix, or whisk together in a bowl.  Pour dressing over vegetables and stir gently to combine.  This recipe will make 1 C of vinagrette which is more than enough, and will be sufficient for a doubling of this side dish.  Add or subtract to the quantities of  the listed vegetables to suit your own tastes and preferences. 

This is a terrific warm-weather salad or side dish and travels well.  Perfect for picnics or barbeques.
