Heat a little olive oil in a small skillet over medium heat. Add the spinach and cover the skillet. Cook until spinach is wilted, stirring occasionally, about 2 minutes, until it has wilted.
Smear the hummus liberally over the naan. Layer with sauteed spinach, sun-dried tomatoes, and pine nuts. Drizzle with pesto sauce and sprinkle with cheese.
Note: You can serve this hot like a hummus pizza by preparing the recipe on a baking sheet and baking at 400 degrees F for 12 to 15 minutes, or until the flatbread is crispy.
