Preheat your charcoal or gas grill over medium high heat. Place Ball Park Park’s Finest franks on the grill and grill for 3-4 minutes until grill marks appear. Once grilled, remove and set aside.
Toast the buns for a few minutes on each side until grill marks appear.
Meanwhile, brush green onions and corn with 1 tablespoon of vegetable oil and sprinkle with salt and pepper. Grill vegetables until slightly charred, turning occasionally, about 2 minutes for green onions and 7 minutes for corn. Cut the corn from cob and transfer the kernels to a bowl. Chop green onions and add to corn. Stir in cilantro, chives, lime zest. Season relish to taste with salt and pepper.
Place a few spoonfuls of guacamole in the toasted bun, followed by the Ball Park Park’s Finest frank, and top with the corn relish and charred jalapeno slices. Serve.
