Preheat the oven to 400°. Line 2 baking sheets with aluminum foil and set aside.
In a large pot, bring the water and 1 tablespoon of salt to a boil. Add the cauliflower, potatoes, Brussels sprouts and turmeric. Cook until just tender, about 5 minutes, and drain.
Meanwhile, in a large skillet, toast the pine nuts over medium heat, stirring constantly, until light golden brown, 4 to 5 minutes. Transfer to a small bowl and set aside.
Return the skillet to medium-high heat and add the oil. When the oil is hot, add the onion, garlic and ginger. Season with salt. Cook until softened, 5 minutes. Add the tomato, garam masala, cumin, coriander and jalapeño, and cook until fragrant and the tomato begins to break down, 3 to 5 minutes more. Remove from the heat and transfer to a large bowl.
To the onion mixture, add the cooked cauliflower mixture, along with the reserved pine nuts and golden raisins. Toss to mix and season with salt. Divide the mixture evenly between the 2 baking sheets and roast until slightly charred, 15 minutes.
Transfer the roasted vegetables to a large serving platter. Garnish with the cilantro leaves and julienned vegetables. Serve with the yogurt sauce. (recipe link below)
Marinate the chicken: Combine the chopped garlic and ginger in a food processor and pulse until almost smooth. In a small skillet, heat the canola oil over medium heat. Cook the garlic and ginger paste, stirring constantly, until fragrant and softened, 3 to 5 minutes. Transfer to a large bowl, along with the yogurt, lemon juice, salt, garam masala, coriander, cumin, turmeric, cardamom and fenugreek leaf, if using. Add the chicken and, using your hands, massage the marinade into the meat, completely covering all of the pieces. Refrigerate for at least 4 hours and up to overnight.
Preheat the oven to broil with the rack about 5 to 6 inches from the heat source. Transfer the chicken to a foil-lined baking sheet. Discard the leftover marinade. Broil until the chicken is cooked through with a few charred spots, 8 to 10 minutes.
Orange Dressing
In a medium saucepan, reduce the orange juice over medium heat to ½ cup, 50 to 55 minutes, adding the thyme after 40 minutes of cooking. Strain the reduced orange juice into a small bowl and whisk in the olive oil and salt. Makes 1 cup and can be made up to 1 day in advance. Cover and store in the fridge, making sure to bring to room temperature 30 minutes before serving.
Mango Garnish
In a large bowl, stir together the mango, tomato, cucumber and lemon juice. Season to taste with salt, stirring every so often until served.
Serve
Place the mixed greens on a large platter and top with the chicken. Drizzle ½ cup of the orange-olive oil dressing on top, serving more on the side. Spoon the mango mixture over top and serve with the mint chutney.
