Preheat the oven to 400 degrees.
Make the vegetable glaze: Mix together the red curry paste, miso paste, agave, olive oil, and sriracha. You will use this before the veggies go into the oven, and again after they come out.
Make the sauce: Put half of the vegetable glaze in another small bowl and whisk in the coconut milk. Taste and adjust for seasonings. Set aside. This sauce is for serving in the roasted veggie bowls.
Prepare the roasted veggies: Line 2 baking sheets with parchment paper or foil for easy cleanup. Arrange the squash and potatoes on one and the leeks, eggplant, and tofu on the other. (The potatoes and squash will have a more similar cooking time than the other veggies).
Brush the veggies and the tofu with the glaze, reserving half to brush more on post-roasting. Place sheets in the oven and start checking at 15 minutes. The leeks, tofu, and eggplant will roast for 15-20 minutes, or until golden brown edges are forming on the tofu and the eggplant breaks down and becomes tender. (Note: the leeks might have to come off first).
Continue roasting potatoes and squash until golden brown, up to 30 minutes.
Once the veggies are removed from the oven, brush more glaze on them while they are still hot. Let them cool for a few minutes and transfer to a large bowl.
Reusing one of the baking sheets, place the chopped chard on it, sprinkle with a few pinches of salt, and place in the oven – roast it for 1 minute; it should be just barely wilted. Remove from oven and place in the bowl with the other veggies.
Toss all the roasted veggies and chard together with the chopped basil. Drizzle the coconut sauce on top and gently toss again. Taste and adjust seasonings.
Top with the toasted sesame seeds and serve with quinoa or rice in the mix or on the side if you wish.
