Oct 7, These roasted spicy seasoned pumpkin seeds have a mild spicy seasoning mix that packs them with flavor. An easy recipe for your leftover. Preheat oven to degrees. In a medium bowl, combine pumpkin seeds, chili powder, cayenne pepper, coarse salt, and fresh lime juice; toss to coat. Spread. Scoop out the inside of your pumpkin, and separate seeds from pulp. Don't worry if there's a little pulp left on the seeds when you roast them—it only adds flavor.
