Slow-Cooker Vegetable & Tofu Thai Stew

Stir together the coconut milk, water, red curry paste, garlic, and lemongrass in a 5- to 6-quart slow cooker until smooth. Stir in the cauliflower, carrots, and onions. Cover and cook on LOW until the vegetables are tender, about 4 hours. Add the zucchini to the slow cooker; cover and cook until the zucchini is tender, about 15 minutes.

Meanwhile, cut the tofu into 1-inch cubes; pat the cubes dry with a paper towel. Heat the oil in a large skillet over medium-high. Add the tofu to the skillet, and cook until deep brown on all sides, 8 to 10 minutes, turning often to brown all sides evenly. Gently stir the tofu, brown sugar, and salt into the slow cooker. Ladle the stew into bowls; top with the cilantro and peanuts.
