I made this again last night and realized I needed to tell you about the recipe calling for 1 tsp. of garlic which is alot! You should alter this to your taste. I think for 4 servings that the ratio is off, unless you are a gungho garlic lover! I think it should be about 1/4 tsp., the same measurement as the basil. I upped the garlic from the 1st time I made it and I only used about 1/4 tsp. and still I thought it was too heavy tasting of garlic.
I never go by the measurement of the spices in recipes. I always eliminate the salt in every recipe. So just be careful on using a full tsp. of garlic! It might ruin the dish! lol.
Rosebird has the best idea! Add the shrimp, chicken or scallops!
