Cooked a large batch of this recipe tonight for my wife and myself using
20 oz. of scallops to ensure plenty of leftovers for tomorrow's meals. It was delicious!
For this amount of scallops I doubled the amount of wine using 1 1/2 cups of Pinot Grigio, minced 6 cloves of garlic (we are both garlic lovers), doubled the fresh basil (1/2 cup), doubled the mushrooms (6 large chopped), doubled the onion powder (1/2 tsp), and kept the rest of the recipe as described. Served with browned rice and steamed broccoli.
Might try it next time adding a splash of McCormick Imitation Butter Flavor. Yummmmm.

Verdict:
Two Thumbs Up!!!
