To make sauce, combine oyster sauce, chicken broth, sherry, sugar and sesame oil in a small saucepan. Bring to a boil, cook, stirring occasionally, until sauce thickens. Remove from stove. Bring 3 to 4 quarts of water to a boil in a large pot. Add salt and peanut oil. Add Mann’s Broccolini®, cook for 3 minutes, until tender and crisp. Drain immediately in colander and shake off excess water. Place on a platter and drizzle sauce over Broccolini®. To eat as a finger food, drizzle only over upper half.
