Toast sesame seeds in large non-stick skillet and set aside.
In a large non-stick skillet over medium heat, warm olive oil. Add garlic and Brussels sprouts. Saute for 15 - 20 minutes, allowing to caramelize as that gives them a lot of flavor. (if they start to burn or stick to the bottom of the skillet, add 1-2 tablespoons of water to delgaze pan. Being careful not to add to much).
When sprouts are brown and tender toss with sherry, sesame oil, and sesame seeds.
