1. Preheat the oven to 375F/190C. Scrub the sweet potatoes and piece the skin of each potato with a sharp knife several times. Arrange on a baking sheet and bake in the preheated oven for 1-1 1/4 hours, or until soft and tender when pierced with the point of a sharp knife. Keep warm.

2. When the potatoes are cooked, bring a pan of water to a boil, add the fava beans and corn, and return to a boil. Reduce the heat, cover, and let simmer for 5 minutes. Trim the green beans, cut in half, and add to the pan. Return to a boil, then reduce the heat, cover, and let simmer for 3 minutes, or until the green beans are just tender.

3. Blend the oil with the vinegar in a small bowl and season to taste with pepper. Drain the corn and beans, return to the pan, ad the tomatoes, and pour the dressing over. Add the torn basil leaves and mix well.

4. Remove the sweet potatoes from the oven, cut in half lengthwise, and open up. Divide the corn and bean filling between the potatoes and serve at once, garnished with basil leaves.
