Bring a large pot of salted water to a boil and set a bowl of ice water nearby. Drop the asparagus into the boiling water and blanch for about 1 minute, until tender but still bright green. Transfer to the ice water for 1 minute, then drain. Transfer the asparagus to a kitchen towel to dry and wipe out the bowl.

At the bottom of the bowl, combine the olive oil, lemon juice, garlic, salt, and pepper. Add the asparagus and peas and toss until coated. Transfer to a platter, drizzle with some of the avocado dressing, top with feta, radishes, pine nuts, and mint or basil.
