Start with an oven proof dish of the appropriate size for the group you'll be feeding. A shallow dish is better than a deep one, because you want a bit of the topping with each scoop. Individual ramekins are nice, and a pie plate works well for larger amounts.
Preheat the oven to 350º.
Fill your baking dish with about a 2 inch layer of hummus.
Top the hummus with coarsely chopped un-toasted pine nuts.
Bake at 350º for about 30 minutes, until the pine nuts are lightly toasted. (Keep an eye on it. Pine nuts burn easily.)
Serve with bread or crackers, olives, fresh or sun-dried tomatoes, and spicy pepperoncini. Oh yeah!
