Press the extra-firm tofu between paper towels for 15 minutes to remove moisture, then cut into 1-inch cubes.
Place the tofu cubes in a bowl and toss with arrowroot powder until each piece is lightly and evenly coated.
Heat the avocado oil in a large non-stick skillet over medium-high heat and sear the tofu until golden and crispy on all sides.
While the tofu cooks, whisk together the tamari, toasted sesame oil, maple syrup, minced garlic, and grated ginger in a small bowl.
Reduce the skillet heat to medium and pour the sauce over the tofu, stirring constantly for 1-2 minutes until the glaze is thick and glossy.
In a large serving bowl, combine the mixed baby greens, shelled edamame, and sliced cucumber.
Top the salad base with the warm, glazed soy-garlic tofu.
Garnish with thinly sliced green onions and sesame seeds before serving immediately.
