Spread the tofu on a greased baking sheet. Add the tamari or soy sauce, oil, ginger, garlic, maple syrup, vinegar, and black pepper. Toss to coat.
Marinate the tofu for at least one hour - or up to four hours.
Pre-head the oven to 425F.
Add the mushrooms, red bell pepper, and onions to the tofu, and toss to combine. Put the baking sheet in the oven.
After 30 minutes, add the sugar snap peas. Bake for 10-15 minutes more, for a total cook time of 40 - 45 minutes, checking and flipping often to ensure even browning of the tofu and vegetables. Remove when the tofu and mushrooms are golden brown and crispy.
If you don't have time to marinate, just omit that step. The flavor will be less intense, but your time will be spared.
Flip it:
Roast tofu with any of your fave veggies such as cauliflower and broccoli instead of mushrooms and peppers.
Swap thinly sliced red onion or shallots for the pearl onions.
