Bring a large saucepan of water to a boil. Add a heaping Tablespoon of kosher salt and the cauliflower. Cook for 3-4 minutes, until cauliflower is tender.
In the meantime, prepare a kitchen towel on a large rimmed baking sheet. After the cauliflower florets are tender, either drain them in a colander or remove them using a slotted spoon. Transfer them to the towel to drain very well. Set aside.
Heat a medium skillet over medium and add the oil. Add the fresh breadcrumbs, chili flakes, and a pinch of salt and sauté breadcrumbs until toasted, about 5 minutes. Set aside.
Heat a large skillet over medium and add the coconut oil. Add the shallots and a pinch of salt and pepper and sauté until the shallots are lightly golden and caramelized, about 6-8 minutes. Remove shallots using tongs or a slotted spoon and set aside.
If the pan looks dry, add more coconut oil. Raise the heat to medium-high and add the cauliflower with a pinch of salt and pepper and sauté until golden, about 6-7 minutes. Do not crowd the pan. Do this in batches, if necessary.
To assemble your dish, scatter the arugula on a platter and arrange the cauliflower on top. Top with breadcrumbs, shallots, pine nuts, and pomegranate seeds. Drizzle with pomegranate molasses and sprinkle with mint leaves. Serve immediately or at room temperature.
