Preheat the oven to 350°. To prepare the sauce, whisk together the sesame oil, peanut butter, five-spice powder, minced garlic, minced ginger, lime juice, maple syrup, and sea salt.

Place tofu in a shallow container and pour the sauce on top. Using your hands, turn the tofu around so that all surfaces are covered. Let it marinate for 15 minutes.

To bake, remove the tofu from the sauce (keeping the sauce handy) and arrange the pieces on a rimmed baking sheet lined with parchment paper. Try to avoid pieces touching one another. Brush generously the top of the tofu pieces with half of the leftover sauce. Transfer the baking sheet to the oven and bake for 15 minutes. Turn the pieces over and baste with the rest of the sauce. Bake for an additional 10-15 minutes, until the tofu is puffed and golden. Remember that the baking time will vary depending on the size of your planks or cubes. Bon appétit!
