To create chocolate-covered pretzel rods, melt chocolate chips in a microwave-safe bowl with vegetable oil. Dip pretzel rods into the melted chocolate using a fork, ensuring an even coating. Place the chocolate-covered pretzels on a baking sheet and add desired toppings. Refrigerate for 15 minutes to set the chocolate. Enjoy as a dessert, snack, or party favor, experimenting with different chocolate types and toppings for a customized treat.
