1. Preheat the broiler. Discard the outermost slices of zucchini and brush the rest with oil; dust with salt and pepper. Place on a baking sheet and broil about 3 inches from heat for 5 minutes on each side, or until tender and slightly browned.
2. Spread 1/4 cup hummus on each wrap and sprinkle with 1 tablespoon pine nuts. Top with a few slices of tomato and zucchini, 1/2 cup spinach, a few sliced onions, and 1 tablespoon mint. Roll up and cut in half on a diagonal.
