Slice the tempeh into bite-sized cubes and season evenly with sea salt and black pepper.
In a small mixing bowl, whisk together the peanut butter, tamari, rice vinegar, sesame oil, and grated fresh ginger until the dressing is smooth.
Heat the avocado oil in a large non-stick skillet over medium-high heat.
Add the tempeh cubes to the skillet and sear for 3 to 4 minutes per side until they are golden brown and crispy.
Reduce the heat to low and pour half of the peanut dressing over the tempeh, tossing for 1 minute to ensure each cube is well-coated and glazed.
Thinly slice the cucumber and place it in a serving bowl along with the shredded carrots.
Top the fresh vegetables with the warm glazed tempeh, drizzle with the remaining peanut dressing, and garnish with sliced green onions and sesame seeds.
