In a large skillet, heat the olive oil over medium heat. Add the Brussels sprouts and shallot and saute until just wilted, about 5 minutes, being careful not to let them burn. Add the lemon zest, juice and pistachios and continue to saute until completely heated through, 3 to 5 minutes. Top with a sprinkle of sea salt.
