Shrimp and Pesto Salad

A recipe I duplicated, originally made by my Aunt Duane Gibb:

1 package of shrimp scampi (sorry, not sure about the amount - I get the
package from Costco)
1 package of bowtie pasta
Artichoke hearts (also from Costco)
Pesto (I get from Safeway)

Because I am not sure about how much of each, just use your best judgment.
