Imonelli's is a local Italian restaurant that serves great Italian food with a South Louisiana influence. The original recipe serves this over pasta, but DH & I prefer to grill whole Portabella mushrooms and serve it over the grilled mushrooms instead of pasta. If you make this change it now becomes a low carbohydrate meal. To grill your Portabellas rinse them under cool water and using a small spoon gently remove the gills on the underside. Rub with olive oil and season to taste. We really like to sprinkle Emeril's Essence on ours then grill. Also, please do not overcook your shrimp or they will be tough and chewy.
