Dry off the potatoes and set them on a plate. Prick a few holes into the potatoes with the tines of a fork. Lightly brush them on all sides with grapeseed oil and sprinkle them with salt. Place the potatoes directly on the oven rack above the baking sheet. Bake the potatoes until tender and the skin feels slightly crisp, about 1-1 ½ hours.

While the potatoes are baking, make the buffalo chickpea filling. Heat a braiser-style pot or deep skillet (with a lid) over medium heat. Drizzle about a teaspoon of grapeseed oil into the pot. Throw the shallots into the pot and sauté until soft and translucent, about 4 minutes. Add the celery and sauté another 2 minutes. Add the paprika and garlic, and stir.

Add the cauliflower and chickpeas to the pot and stir again. Pour in the vegetable stock and stir to combine. Add the tomatoes and Buffalo sauce and stir. Season the mixture with black pepper and bring it to a boil. Let the buffalo chickpea mixture simmer, covered, until the cauliflower is tender, about 6 minutes. Remove from the heat.

Once the potatoes are baked and you can handle them, cut them in half lengthwise. Lay the halves on a parchment lined baking sheet. Scoop out 1 tablespoon or so of potato from each half. You can eat this cooked potato on the spot or save it for another use. Lightly mash the insides of the potatoes with a fork.

Gently spoon the buffalo chickpea mixture into the baked potato halves. Slide the baking sheet into the oven and bake potatoes for another 12-15 minutes, or until the buffalo chickpea filling is hot.

Serve twice baked potatoes hot, topped with extra black pepper, extra hot sauce, chopped parsley, and celery leaves.
