Add beans to boiling water and cook for 4 minutes, stirring occasionally (if your beans are really small and thin, only cook for 3½ minutes). Drain well and immediately plunge into the bowl of ice water (this will stop the cooking process) then drain again and allow to sit for 5 minutes. Shake strainer occasionally to remove as much water as possible.
Spread drained beans out on several thicknesses of paper toweling or a clean kitchen towel and pat to dry as much as possible. At this point, beans can be wrapped in dry paper towels, placed in a ziplock bag and refrigerated till just before serving.
When ready to serve, heat a large sauté pan over medium heat. Add sauce and stir continuously for 1-2 minutes or until sauce is bubbly and starting to thicken slightly.
Add green beans and stir gently for 2-3 minutes or until veggies are glazed and warmed through. Add peas and sprinkle with about ½ teaspoon of kosher or regular salt and a generous grind of fresh pepper. Stir again for 30 seconds. Sprinkle with light and black sesame seeds. Serve hot, cold or at room temperature.
