Bring a pot of water to a boil over high heat. Once boiling, season water with kosher salt.
While water is boiling, wash asparagus and cut it into 2- to 3-inch pieces, cutting on sharp angle.
Add cut asparagus to the boiling water and set a timer for 90 seconds. After that time, add in shelled English peas and blanch for another 90 seconds.
Drain asparagus and peas into a colander and rinse with cold water to stop the cooking.
Meanwhile, make the Mint-Infused Vinaigrette by adding minced shallot, mint-infused olive oil and white balsamic vinegar to a small bowl. Whisk vigorously to emulsify and season with kosher salt and cracked black pepper.
