What a beautiful dish! And boy, did I look like a pro with this. I've seen chefs on TV use this technique, so I was familiar with it. The shrimp steamed beautifully on a bed of couscous. I did saute the onions first (personal preference) and I added lemon zest to the shrimp before the pesto. It was an easy, impressive dish. I used the microwave to heat the chicken stock in a measuring cup and mixed the couscous right into that, so there was very little cleanup. I will be making this again. Thanks so much for posting!
