Shrimp and String Bean Pesto Pasta

I can’t get this meal out of my mind. I blame the walnut pesto sauce. The plump, sweet shrimp. The fresh, tender string beans. And  the chewy, rotini pasta. Because one humble ingredient can cause a meal to be entirely unforgettable but the sum of its parts deserve credit too.

The fresh, earthy pesto walnut sauce ties everything together, enhancing and bringing out everyone’s best qualities.

If you have the pesto sauce made ahead of time, which I recommend to allow the flavors to marry and mingle, then this comes together in the short time it takes to cook pasta. Trim the string beans while the water toils to a boil then toss them right in with the pasta. Or, if you prefer, put your steamer basket right over the pasta and steam your little string bean’s heart out. While the pasta and beans cook saute the shrimp.

Toss all that deliciousness together with the pesto sauce and call it dinner time.

No one has to know how fast and easy it really was to create.

Because it will appear as if you slaved over the hot stove for at least an hour. If not longer.
