Preheat the oven to 425°F. Arrange the potatoes on a baking sheet and lightly spray with high heat oil. Sprinkle with sea salt then bake in the oven for 30 minutes, stirring half way through. Set aside to cool
Meanwhile, bring a large pot of water to a boil. Add the asparagus and peas then cook for about 5 minutes. Strain and rinse with cold water to stop the cooking process.
In a measuring cup, whisk together the lemon juice, chopped dill, vinegar, dijon mustard and olive oil. Set aside.
Once the potatoes have cooled, transfer them to a large bowl. Add the asparagus, peas, leek, and radishes. Pour the dressing on top and toss until evenly coated. Serve immediately and enjoy!
