The Inspiration

Grilling fresh vegetables and seafood is one of the best ways to bring out natural flavors while creating a meal that feels both rustic and refined. This recipe draws inspiration from Mediterranean-style cooking, where fresh produce, high-quality seafood, and bold yet balanced sauces come together to create dishes that are simple, nourishing, and full of character.

On Fresh Market Dinners, Amanda Herrera showcases recipes that celebrate seasonal ingredients and creative ways to prepare farmers’ market finds. This Grilled Fennel and Kale with Tuna recipe transforms familiar ingredients into an elevated dish by grilling fennel and kale until lightly charred, enhancing their natural sweetness and adding smoky depth. The seared tuna provides a rich, protein-packed centerpiece, while the tahini miso dressing adds creamy umami flavor that ties all the elements together.

Fennel brings a subtle licorice-like sweetness that mellows beautifully on the grill, while kale develops a crisp, smoky texture that balances the richness of the tuna. Finished with bright green peas and delicate fennel fronds, this dish is a celebration of fresh flavors, textures, and seasonal cooking.

Ingredients

2 large bulbs of fennel
1 bunch of kale
4 tablespoons (75 ml) extra virgin olive oil, divided + more for drizzling
Salt and pepper
4 red tuna steaks, 6-7 ounces (170-198 g) each
1 cup (240 ml) freshly shelled peas
1 cup (240 ml) Tahini Miso Dressing (see recipe)

Method

Remove stalks from fennel bulbs, reserving the fronds. Cut fennel bulbs in half lengthwise and then cut into wedges. Trim off the woody ends of the kale, keeping stem and leaves intact. Brush fennel wedges and kale leaves with 4 tablespoons of oil and season with salt and pepper.
Place fennel on grill and cook for 4-5 minutes over medium-high heat. Flip and cook for another 4-5 minutes. Once charred and slightly soft, add kale leaves to grill. Cook for 1 -2 minutes, flip and cook for another 1-2 minutes. Remove kale and fennel from grill and reserve for plating.
Heat large skillet over medium-high heat and add remaining 2 tablespoons of oil. Season tuna with salt and pepper in skillet. Sear for 2 minutes. Flip and sear for another 2 minutes on the other side. Remove tuna from skillet and let rest for 3-5 minutes.
On a serving platter, place charred kale and top with grilled fennel wedges. Cut tuna steaks in half lengthwise and place on top of the fennel.
Drizzle with Tahini Miso Dressing (see recipe). Garnish with fresh peas and fennel fronds.
