Score the skins with a sharp knife in an X on the bottom of each tomato. Place the tomatoes in boiling water for 30 seconds, then transfer to ice water bath to cool. Peel, halve, and slice tomatoes, and reserve.
Preheat the oven to 425ºF.
Toss the squash with a drizzle of extra-virgin olive oil and season with salt, pepper, and nutmeg. Arrange the squash on a baking sheet and roast 25 to 30 minutes, until tender and brown at edges.
Heat 2 tablespoons extra-virgin olive oil in a large skillet with tight fitting lid. Add the peppers, onions, garlic, ginger, and season with salt and pepper, sweat out the vegetables a few minutes then add the eggplant, curry, chile powder, and cardamom. Stir to toast and combine, then cover the pot and cook 12 to 15 minutes, stirring occasionally, until eggplant is tender. Stir in the roast squash, tomatoes, chutney, and stock. Cool and store for make-ahead meal.
If serving immediately, start the rice a few minutes after the squash goes into the oven. Otherwise, reheat the curry over medium heat, stirring occasionally, 15 minutes after you start cooking the rice. To prepare the rice, follow package directions adding lime zest or leaves to water before rice, add the scallions to the rice and lime juice when the rice is done and you fluff with fork.
