To assemble salad:
Preheat oven to 375°F. Toss the chopped asparagus, olive oil and salt and pepper and spread in a single layer on a sheet pan. Roast until fork tender, about 10-15 minutes (depending on size, adjust time as needed). Cool slightly.
Toss the roasted asparagus, chopped avocado and mixed greens with some lemon-vinaigrette. Serve immediately.
Note: Store leftover vinaigrette in the fridge for up to several weeks. Let come to room temperature for about 5 minutes, then shake to reincorporate.
