Prepare your rice according to the package instructions.
Whisk all the sauce ingredients together until well combined, thinning with water to reach desired consistency. Taste, and adjust if you'd like.
Spoon as much of the hot cooked rice as you'd like into a large bowl. Top with the greens, edamame, asparagus, cucumber, and avocado. Spoon on as much sauce as you want, followed by the herbs and gomasio.
Store any leftover rice and sauce in sealed containers in the refrigerator for up to one week.
