Hold the end of an asparagus stalk and bend until it snaps off. Repeat with remaining stalks and discard woody ends. Slice trimmed spears on the diagonal into 1/8-in. lengths, leaving tips about 1 in. long.
Remove and discard outer leaves of lettuce heads. Tear remaining leaves into bite-size pieces. Rinse and dry. Set aside.
In a small bowl or measuring cup, whisk together olive oil, lemon juice, honey, salt, lemon zest, pepper, and dry mustard until creamy-looking.
In a large bowl, toss lettuce with 3 tbsp. dressing. Divide lettuce among 4 salad plates. Toss asparagus pieces with remaining dressing and spoon over lettuces, dividing evenly. Sprinkle salads with perlini and pine nuts. Serve immediately.
