In a medium bowl, toss together the nectarines, thyme, orange zest, sugar, and 1/2 tsp. salt. Add 1 Tbs. of the oil and toss to coat. Let stand for 10 minutes.
In a small bowl, combine the vinegar, honey mustard, 1/2 tsp. salt, and a few grinds of pepper. Gradually whisk in the remaining 3 Tbs. of oil.
In a large bowl, toss the greens with enough vinaigrette to lightly coat. Add the nectarines and toss to combine. Divide the mixture among the serving plates, sprinkle with the Gorgonzola, and serve.
