Peel celeriac, wash, quarter and thinly slice. Add to a mixing bowl.
Gently melt the coconut oil in a saucepan on a low heat. Pour over the celeriac, add fennel seeds, salt and pepper. Gently press each garlic clove (x6), skin on, under the palm of your hand to slightly open it and allow the juices and aroma to seep out during cooking. Toss in with the celeriac and mix well by hand. The celeriac should feel well-coated with the coconut oil.
Roast this seasoned celeriac in a baking tray. Cover with foil for 20 minutes to steam and sweeten. Then, discard the foil, gently shake the celeriac to ensure that it is not sticking to the tray, and continue to roast for 30 minutes until golden brown and tender. Allow to cool in the tray. Gently squeeze the roasted garlic out of their skins, discard the skins and add the gooey, delicious flesh to the celeriac.
While the celeriac is cooking, make the herb dressing using a food processor. Add the pumpkin seeds and crushed garlic and blend until a fine ‘breadcrumb’ using the blade attachment. Wash and roughly chop the herbs (including the stalks). Add half to the food processor with half of the olive oil, and quickly blend (for under a minute) until smooth. Turn off, add the salt and remainder of the herbs and olive oil, and then quickly blend again until a smooth pesto-like consistency. Add an extra drizzle of olive oil if you feel that the sauce is slightly dry.
To assemble the salad: in a large bowl, combine the cooked chickpeas, roasted celeriac and garlic, pomegranate seeds, crumbled feta and herb dressing. Just before serving, add the juice of a whole lemon, check that you are happy with the seasoning (add more salt, pepper and/ or lemon juice to your taste) and serve immediately.
