Heat oven to 400 degrees F. Put pumpkin on rimmed baking sheet. Sprinkle with salt and pepper, drizzle with oil and toss to coat. Arrange in a single layer. Bake 20 minutes or until edges just begin to color and pieces become tender. Shake pan gently to test for pumpkin sticking; release any pieces with a flat spatula. Sprinkle the pecans, garlic, and sage leaves over pumpkin and toss gently. Roast 7 minutes longer and serve.
