Cut off top of bread loaf and remove the center of the bread to leave about a 1/2 inch crust. Brush with olive oil and place in a warm oven until dry and crisp, checking regularly. Remove and cool.
Vegetables
Trim and prepare all vegetables, mix together in a large bowl.
Mix together all dressing ingredients and pour over the vegetables. Stir well and cover, allowing vegetables to marinate over night. ( with the exception of the green beans or zucchini.)
Add 1 cup sliced zucchini or trimmed green beans to vegetable mixture. Spoon into bread loaf with a slotted spoon and serve.
