Pesto Without a Pestle

My basil plant has been very good to me this summer. I had enough basil to make a pesto sauce for dinner. Traditionally pesto is made with a mortar and pestle, but being that I have no more kitchen space for one I used my food processor. It was very simple to make but I lacked one ingredient, pine nuts. After researching online, I found out that sesame seeds can be substituted to create the same texture. It really does work. The pesto was tossed with linguine. The fish was tilapia. I put the pesto on the fish for the last few minutes while under the broiler. Tilapia can be bland but the flavorsome pesto made it delicious.
