re: What's your favorite crawish Monica recipe?

I have the original recipe from when they first started selling their Pasta Fresca in the 1980's. Monica told me she has since changed the recipe. Here is the original:
1 Stick butter
3/4 Cup chopped green onions
1 lb Crawfish tails
1 TBL Cajun Magic-Seafood Magic
1 Pint Half and Half
Melt butter in large saucepan, saute onions for 2-3 minutes. Add Cajun Magic and crawfish tails. Saute for one minute. Add half and half and cook for 5-10 minutes until sauce thickens. Add pasta and toss well.Serves 4.
