Also, this lasts surprisingly well as leftovers. Maybe I got lucky, but since there isn't too much lettuce there wasn't really anything to get soggy from the dressing.
I think the most fun part is that we grilled grapes. I know I've had grilled pineapple and peaches before, but grapes are novel. We just put them on the fire in a veggie basket and they cooked up great! ("We" really equals the guys who did the grilling and thought I was nuts.)
 | Celery, Grilled Grape and Mushroom Salad 6 servings 2 Tbsp. white wine vinegar 2 tsp. fresh lemon juice ½ tsp. celery seeds ¼ tsp. Dijon mustard 2 small garlic cloves, minced ½ cup plus 1 Tbsp. extra-virgin olive oil, plus more for brushing ¼ cup roasted almond oil Salt and freshly ground pepper ½ cup flat-leaf parsley leaves ½ cup tender celery leaves (from one head) ¼ cup salted roasted almonds, chopped 1 pound king oyster mushrooms, sliced lengthwise ¼-inch thick 2 cups green grapes (12 ounces) 2 heads butter lettuce, leaves separated 2 cups very thinly sliced celery |
In a small bowl, whisk the vinegar with the lemon juice, celery seeds, mustard and half of the garlic. Gradually whisk in ¼ cup of the olive oil and the almond oil until emulsified. Season the dressing with salt and pepper.
In a mini food processor, combine the remaining garlic with the parsley,c elery leaves and almonds nad pulse until finely chopped. Add another ¼ cup of the olive oil and puree to a chunky paste. Season the pesto with salt and pepper.
Light a grill. Brush the mushrooms with oil and season with salt and pepper. Grill over high heat, turning once, until tender and browned, about 5 minutes. In a bowl, toss the grapes with the remaining 1 tablespoon of olive oil and season with salt and pepper. Grill over high heat until the skins begin to blacken in spots, about 3 minutes; line the grill with perforated foil if the grapes will fall through. Transfer the grapes and mushrooms to a large bowl and toss with the pesto.
Arrange the lettuce leaves on a platter and drizzle with half of the dressing. Spoon the mushroom-and-grape salad onto the lettuce. Toss the celery with the remaining dressing, spoon it on top and serve.
