Orzo is a Greek pasta shaped like grains of rice.
Cook orzo according to package directions. Melt butter in a medium saucepan over medium heat. Add shallot and lemon zest, and saute until translucent.
Add peas, and cook until bright green and tender, adding a little water if shallots brown before peas are tender.
Add cooked orzo, season with salt and pepper, and toss to combine. Remove from heat, and stir in mint.
