Heat oven to 425 degrees. Prick the potato a few times with a fork. Bake directly on the middle rack for 40 minutes or until tender.
When the potato is almost done baking, saute the zucchini in a medium-small nonstick skillet over medium heat in the oil until tender. Season with red pepper flakes to taste.
While the zucchini is sauteing, fold the tomatoes, cucumber, basil, lemon juice and zest, oregano, salt, and pepper together.
Place the potato in a medium-large bowl, then split. Season with salt and pepper. Top with the hummus. Spoon the zucchini over the hummus, followed by the tomato salad.
