Combine garlic, oil, curry powder, chili powder, and salt in a small bowl. Mix well.
Combine the broccoli, eggplant, chickpeas, and sliced red onion in a large mixing bowl. Add the spice-oil mixture to it. Toss everything together until the vegetables and chickpeas are well coated.
Spread the mixture in a single layer on a large baking sheet. Roast in the preheated oven for 25-30 minutes, stirring halfway through, until the vegetables are tender and slightly browned and the chickpeas are crispy.
Once roasted, remove the vegetables from the oven. Squeeze fresh lemon juice over them. Garnish with chopped fresh cilantro.
Make the mint chutney sauce
Combine cilantro, mint leaves, green chili, red onion, ginger, peanuts, yogurt, and salt in a blender. Blend until smooth and creamy.
Serve:
Serve the Indian-inspired roasted broccoli, eggplant, and chickpeas warm with cooling mint chutney sauce. They can be enjoyed on their own or as a side dish. Turn them into a bowl by serving them over a bed of basmati rice or with naan bread.
Notes
Ensure your oven is fully preheated before roasting. This helps to ensure even cooking and caramelization of the vegetables.
Cut the broccoli and eggplant into uniform pieces so they cook evenly. This ensures that all pieces are done at the same time.
Pat dry the chickpeas with a kitchen towel before roasting. Dry chickpeas will become crispier in the oven.
Spread the vegetables on the baking sheet in a single layer. Overcrowding can cause them to steam instead of roast, leading to soggy results.
