An EASY quick and delicious meal. I make my own pesto and freeze small batches for meals like this but you definitely can use store bought. You can substitute the Heavy Cream with Half and Half or Light Cream. The sauce is made in a medium fry pan in no time and will sit fine covered until your pasta is done. I suggest Lunguini or regular Spagetti with a nice bottle of dry white wine and toss salad. This will have some calories to it but once in a while splurge! This is worth it. I made this up in less time it took to boil the water.
