Place cauliflower, chickpeas, tomatoes, carrots, garlic, curry powder, honey, grated ginger, red pepper flakes, 2 teaspoons salt, and black pepper in a large resealable bag.
Press out as much air as possible and seal the bag tightly.
Freeze the bag flat in the freezer for up to 3 months.
The night before cooking, thaw the freezer pack in the refrigerator for at least 24 hours.
Pour the thawed contents into a 6-quart slow cooker and spread evenly.
Cook on low for 7 to 9 hours, until the cauliflower is fork-tender but not falling apart.
Stir in the coconut milk gently to coat the ingredients without breaking apart the cauliflower.
Taste and adjust seasoning with more salt and black pepper as needed.
Serve hot with fresh lime wedges, chopped cilantro, and a sprinkle of cashews for crunch.
