Vegan Sweet Potato Casserole with Pecan Crumble

Directions

1. Poke holes all over sweet potatoes with a fork, then place them on a large microwave-safe plate. Microwave on high for 15-20 minutes, until potatoes are very tender when pierced with a fork. (Microwave in batches if necessary.) Carefully remove plate from the microwave and allow sweet potatoes to rest for about 15 minutes, or until cool enough to handle.
2. Preheat oven to 375°F.
3. Spray a 9x13-inch casserole dish with nonstick cooking spray.
