Walnut Harissa
6 hot to mild dried chiles like ancho, chile de arbol, guajillo, or a blend
5 tbsp/75 ml neutral-flavored extra virgin olive oil or grapeseed oil
1 large garlic clove
2 tsp sweet paprika
1 1/2 tsp ground coriander
1/2 tsp cayenne pepper
1/2 tsp ground cumin
1 large carrot, peeled and finely grated
½ cup finely chopped walnuts
1 tbsp fresh lemon juice
½ tsp sea salt, plus to taste
2 roasted red peppers, seeded
3/4 cup Non-fat or low-fat Greek yogurt
1 fresh whole wheat baguette, or 4 whole-wheat soft rolls, split
Melted unsalted butter, for brushing
1/2 medium bulb fennel, quartered and cored
Handful of sharp or spicy lettuce, such as arugula/rocket
3 tablespoons extra-virgin olive oil
Sea salt
Freshly ground black pepper
Six 4-ounce/170 gram black or striped bass fillets, scaled and pin bones removed
1 teaspoon fennel seeds, crushed
Hearty pinch of red pepper flakes
1 medium cucumber, peeled and thinly sliced
Yield (for harissa): 1 2/3 cups
Add the chiles, 1tbsp of their steeping liquid, and the roasted red peppers to a blender or mini food processor and puree to make a paste. While running, slowly pour in the garlic, spices, and oil to thicken the paste. Taste and season with salt and lemon, adding a touch at first and the whole amount as needed. Set aside 1 cup of the walnut harissa in an airtight container in the fridge. Stir the remaining harissa into the Greek yogurt and set aside for dressing the sandwiches.
Slice the fennel as thinly as possible with a sharp knife or mandoline. Toss the lettuce and sliced fennel with 1 tablespoon of the olive oil in a bowl and sprinkle with salt and freshly ground pepper. Set aside.
Heat 2 tablespoons of the oil in your largest nonstick skillet over medium-high heat. Add the fish, skin-side down, and cook until the skin is golden and crisp, about 4 minutes. Meanwhile, pop your bread under the broiler for a few minutes until crisp and golden. Using a flexible metal or fish spatula, gently turn the fish over and cook the flesh side until just cooked through, about 1 minute more. Remove from the pan and set on a plate.
