Delicious Grilled Salmon Sandwich

Ingredients:
2 lbs fresh salmon fillets
extra virgin olive oil
kosher salt
fresh ground pepper

FOR THE SAUCE
1 cup good mayonnaise
1/4 cup sour cream
3/4 teaspoon white wine vinegar
12 fresh basil leaves
3/4 cup chopped fresh dill
1 1/2 tablespoons chopped scallions (white and green parts)
1/4 teaspoon kosher salt
1/4 teaspoon fresh ground black pepper
3 teaspoons capers, drained

TO ASSEMBLE
6 fresh white rolls or brioche bread (4-inch round)
1/4 lb fresh basil leaf

Directions
1. For the salmon, heat coals in an outdoor grill and brush the top of the grill with oil.
2. Rub the outside of the salmon with olive oil, salt, and pepper, to taste.
3. Grill for 5 minutes on each side, or until the salmon is almost cooked through.
4. Remove to a plate and allow it to rest for 15 minutes.
5. For the sauce, place the mayonnaise, sour cream, vinegar, basil, dill, scallions, salt, and pepper in the bowl of a food processor fitted with a steel blade.
6. Process until combined.
7. Add the capers and pulse 2 or 3 times.
8. To assemble the sandwiches, slice the rolls in 1/2 crosswise.
9. Spread a tablespoon of sauce on each cut side.
10. On the bottom 1/2, place some mesclun salad and then a piece of salmon.
11. Place the top of the roll on the salmon and serve immediately.
12. (I like to toast the rolls on the grill too) Enjoy!

Sounds dee-licious!
