Drain tofu and cut into cubes. If you have time, let the tofu sit in a bowl for at least 10 minutes. It will naturally release water as it sits.
Add avocados, cucumbers, and tomatoes to a bowl. Drain any excess water from the tofu, then add tofu to the bowl with the veggies.
Spoon green onion sauce on top and gently mix, then sprinkle with any other toppings you'd like. Serve immediately.Tip: If you don't have green onion sauce, whisk all the dressing ingredients together until the sugar dissolves. Pour over the salad.
