Preheat your oven to 250°F / 120°C.
Place the baked seasoned tofu and its marinade into a baking dish and place it in the oven to warm gently while you prepare the vegetables.
Heat 2 tablespoons (30 ml / 1 fl oz) of olive oil in a large, heavy skillet (cast iron is ideal) over medium-high heat. A quick tip: turn on your exhaust fan now to avoid a smoky kitchen!
Once the oil is shimmering, carefully place the Brussels sprouts cut-side down in a single layer.
Sear for 2 to 3 minutes until deeply browned, then flip and cook for another 3 to 5 minutes until tender and charred in spots.
Transfer to a baking sheet, season with salt and pepper, and place in the warm oven.
Add another 2 tablespoons (30 ml / 1 fl oz) of oil to the same skillet.
Arrange the squash slices in a single layer and cook for about 3 minutes per side, until golden brown and tender.
Work in batches if necessary, adding more oil as needed.
Season with salt and pepper and add the cooked squash to the baking sheet with the Brussels sprouts.
Sprinkle the chopped fresh mint over all the warm vegetables.
To serve, slice the warm tofu into strips.
Divide the cooked wild rice among your bowls and drizzle a little of the reserved tofu marinade over it.
Top generously with the seared Brussels sprouts and squash, arrange the tofu strips on top, and enjoy immediately.
Don't overcrowd the pan.
Cook vegetables in a single layer, working in batches if needed, to ensure they sear rather than steam.
Turn on your exhaust fan before you start searing the Brussels sprouts; the oil gets very hot and can set off a smoke alarm.
