Press the extra firm tofu for at least 15 minutes using a tofu press or heavy skillet to remove excess moisture, then cut into 1-inch uniform cubes.
In a small mixing bowl, whisk together the creamy peanut butter, tamari, lime juice, sriracha, minced ginger, and minced garlic until the sauce is completely smooth.
Place the tofu cubes in a bowl and toss with the nutritional yeast, sea salt, and black pepper until each piece is well-coated.
Heat the sesame oil in a large non-stick skillet over medium-high heat until shimmering.
Add the tofu to the skillet in a single layer and sear for 3-4 minutes per side, or until all sides are golden brown and crispy.
Add the broccoli florets and shelled edamame to the pan with two tablespoons of water; cover with a lid and steam for 3 minutes until the broccoli is tender-crisp.
Remove the lid and pour the peanut sauce over the tofu and vegetables, tossing gently for 1 minute until the sauce thickens and glazes the ingredients.
