1. Preheat the oven to 400 degrees F. Place the zucchini on a baking sheet. Drizzle with the olive oil, then sprinkle with 1 teaspoon salt; mix well and spread to 1 layer. Roast until browned and very tender, about 30 minutes, stirring halfway through.
2. Warm the pita on a grill or griddle until nicely toasted, but still soft, and spread each with 1 heaping tablespoon hummus. Top each piece with 1 tablespoon crumbled goat cheese, 1/4 of the roasted zucchini, about 1/2 cup baby arugula, and 1 tablespoon coarsely chopped almonds. Serve with a lemon wedge.
