Preheat oven to 400°F and line a baking sheet with parchment paper.
Press the tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
Toss tofu with sesame oil, sea salt, and black pepper, then spread in a single layer on the baking sheet.
Bake for 25-30 minutes, flipping halfway through, until the edges are golden and crispy.
While tofu bakes, whisk together peanut butter, Greek yogurt, tamari, sriracha, lime juice, grated ginger, and minced garlic in a small bowl.
Steam the edamame and thinly slice the red bell pepper.
Toss the crispy tofu and edamame in the peanut sauce until well coated.
Serve immediately topped with the fresh bell pepper slices.
