1. Preheat oven to 350 degrees Fahrenheit. Line a rimmed baking sheet with foil and grease with oil.
2. Melt the margarine in a sauté pan over medium heat. Add pepitas, toss to coat, then add sugar, cinnamon, ginger, allspice, cloves, and kosher salt. Spread pepitas on the prepared baking sheet in a single layer and cook, stirring once or twice, until golden brown all over, eight to 10 minutes. Cool completely.
