Once the tough ends are removed, rinse the asparagus, pat dry and cut into 2” pieces.
Preheat the oven to 400° F.
Put the asparagus pieces in a large mixing bowl. Drizzle with olive oil and season lightly with salt and freshly ground black pepper. Toss to coat.
Lightly oil a large baking pan with 1” sides. Arrange the asparagus in a single layer for even roasting. Roast for 15 to 20 minutes, or until tender. Once done, place the pan of roasted asparagus on a wire rack to cool.
To make the vinaigrette:
Place all of the dressing ingredients in a jar with a tight-fitting lid. Shake vigorously until ingredients are blended. Note: Be sure to shake the vinaigrette before each use, as the oil and vinegar will separate each time the vinaigrette has time to rest.
To Assemble the Salad:
In a mixing bowl, combine the cut tomatoes with the crumbled Feta and gently toss them together with some of the shaken vinaigrette.
Arrange the roasted asparagus on a serving platter. Drizzle with a little more of the vinaigrette.
Arrange the tomato and Feta on top of the asparagus. Finally, add the basil or mint leaves. This salad may be served warm, at room temperature, or chilled.
