Drain the firm tofu and press it between paper towels for 10 minutes to remove excess moisture.
Cut the pressed tofu into 1-inch cubes and season evenly with sea salt and black pepper.
In a small bowl, whisk together the tamari, half of the sriracha, rice vinegar, garlic powder, and ginger powder to create the glaze.
Heat the toasted sesame oil in a non-stick skillet over medium-high heat and sear the tofu cubes until golden and crispy on all sides.
Pour the tamari glaze mixture over the tofu in the skillet and toss for 1 minute until the sauce thickens and coats the cubes.
Steam the broccoli florets and shelled edamame in a steamer basket until tender-crisp, about 4 to 5 minutes.
In a separate small bowl, stir together the non-fat Greek yogurt and the remaining sriracha to create a spicy protein-packed crema.
Assemble the bowls by layering the cooked quinoa, steamed broccoli, edamame, and the glazed tofu, then finish with a dollop of the spicy crema.
