Preheat oven to 350 degrees F. Spray an 8″ square pan with cooking spray and set aside.
Cook and drain pasta according to package directions.
While pasta cooks, heat a large skillet over medium-high heat. Add MELT spread, and cover pan immediately until melted and spattering has stopped. Whisk in flour until smooth. Add milk about 1/4 cup at a time, whisking constantly until smooth before adding more. Continue until all milk is incorporated. Bring to low simmer.
Reduce heat to medium, and stir in cheese until melted. Stir in pumpkin, salt, garlic powder, worcestershire sauce, and pepper. Cook and stir briefly until heated through. Add cooked pasta, and stir to coat.
Transfer mac and cheese mixture to the prepared baking dish. Stir together melted MELT and cracker or bread crumbs. Evenly spread crumb mixture over pasta. Bake in preheated oven for 25 minutes.
Don’t go out and buy worcestershire sauce just for the recipe. If you don’t have it on hand, you can leave it out.

Take it from me: Don’t tell your kids about the pumpkin.
