Couscous with peas and mint

This is a delicious side dish for the summer. The pine nuts add texture and the mint is an great unexpected flavor. It's another Barefoot Contessa creation!  I just bought her new cookbook and have been trying everything from it.

3 tbsp olive oil
1 tbsp unsalted butter
1/2 cup shallots, chopped
3 1/2 cups chicken stock
2 cups couscous
12 oz frozen peas, defrosted
1/2 cup fresh mint leaves, chopped
1/3 cup toasted pine nuts

Heat the oil and butter in a large saucepan over medium heat.  Add the shallots and cook over medium-low heat for 4 minutes, stirring occasionally.  Add the stock and bring to a boil.  Stir in the couscous, 1 tsp of salt and 1/2 tsp pepper and put the lid on.  Turn off the heat and allow the couscous to steam for 10 minutes.  With a fork, fluff the couscous and stir in the peas, mint and pine nuts.  You can add more salt and pepper to taste,
