Preheat the oven to 400°F
Place the sweet potatoes and purple potatoes in a large bowl. Pour 2 tablespoons of the olive oil over top and add 1 teaspoon of the salt. Toss to coat.
Transfer the potatoes to a baking sheet lined with parchment paper. Place the pan in the oven and roast for 20 minutes, turning once, or until golden brown.
While the potatoes are roasting, coat the corn in the remaining olive oil. Sprinkle the gochugaru evenly over the corn and repeat with the remaining salt.
Oil a cast iron griddle pan with a little vegetable or coconut oil and place over high heat until smoking. Add the corn and grill on all sides until blistered, about 5 minutes. Transfer the corn to a plate and set aside to cool slightly.
Once the potatoes are done, transfer them to a large bowl. Add 1/4 cup of the scape miso pesto and toss to coat. Divide the potatoes amongst four bowls and set aside.
Cut the corn off of the cobs and sprinkle the kernels over each bowl of potatoes. Top with smashed wasabi peas, nori ribbons, avocado slices and a sprinkling of sesame seeds. Serve immediately with a light Asian beer.
