Yes, orchid, part of the marinade goes into the salad dressing. I sometimes boil the part of the
marinade the pork was in so I can add some of it, too, if I think the dressing needs more. No, I have never tried leaving scallions or mushrooms raw, but don't see why that wouldn't fly. Would cooking them add additional flavor perhaps? I have no idea--just a question to consider. I've always made this recipe as written.
For your consideration, here is ANOTHER pork tenderloin salad recipe from epi that does exactly as you asked and whisks some olive oil into the dressing. It is called Island Pork Tenderloin Salad and is also quite tasty. This one might be more to cheezz's liking since she's headed to Maui. It got a 4 out of 4 star rating. There is a picture of it at the link.
ISLAND PORK TENDERLOIN SALAD from GOURMET, May, 2003
Makes 6 to 8 main course servings
Ingredients
For pork
2 teaspoons salt
1/2 teaspoon black pepper
1 teaspoon ground cumin
1 teaspoon chili powder
1 teaspoon cinnamon
2 pork tenderloins (2 1/4 to 2 1/2 pounds total)
2 tablespoons olive oil
For glaze
1 cup packed dark brown sugar
2 tablespoons finely chopped garlic
1 tablespoon Tabasco
For vinaigrette
3 tablespoons fresh lime juice
1 tablespoon fresh orange juice
1 tablespoon Dijon mustard
1 teaspoon curry powder, toasted
1/2 teaspoon salt
1/4 teaspoon black pepper
1/2 cup olive oil
For salad
3 navel oranges
5 ounces baby spinach, trimmed (6 cups leaves)
4 cups thinly sliced Napa cabbage (from 1 medium head)
1 red bell pepper, cut lengthwise into thin strips
1/2 cup golden raisins
2 firm-ripe California avocados
Special equipment: an instant-read thermometer
Preparation
Prepare pork:
Preheat oven to 350°F.
Stir together salt, pepper, cumin, chili powder, and cinnamon, then coat pork with spice rub.
Heat oil in an ovenproof 12-inch heavy skillet over moderately high heat until just beginning to smoke, then brown pork, turning, about 4 minutes total. Leave pork in skillet.
Make glaze and roast pork:
Stir together brown sugar, garlic, and Tabasco and pat onto top of each tenderloin. Roast in middle of oven until thermometer inserted diagonally in center of each tenderloin registers 140°F, about 20 minutes. Let pork stand in skillet at room temperature 10 minutes. (Temperature will rise to about 155°F while standing.)
Make vinaigrette while pork roasts:
Whisk together juices, mustard, curry powder, salt, and pepper, then add oil in a stream, whisking until emulsified.
Prepare salad ingredients while pork stands:
Cut peel, including white pith, from oranges with a sharp knife, then cut oranges crosswise into 1/4-inch-thick slices. Toss spinach, cabbage, bell pepper, and raisins in a large bowl with about 1/4 cup vinaigrette. Halve, pit, and peel avocados, then cut diagonally into 1/4-inch-thick slices.
Assemble salad:
Cut pork at a 45-degree angle into 1/2-inch-thick slices. Line a large platter with dressed salad and arrange sliced pork, oranges, and avocados in rows on top. Drizzle some vinaigrette over avocados and oranges. Pour any juices from skillet over pork.
