Steps
- If using wooden skewers, soak them in water for 20 minutes. Preheat the grill to medium-high, about 450°F (232°C).
- Make the marinade: whisk half of the olive oil with the smoked paprika, garlic, oregano, lemon zest, half of the lemon juice, the black pepper and half of the salt.
- Toss the tuna in half of the marinade; set aside for 15 minutes.
- Toss the red bell pepper, green bell pepper, broccoli and red onion with the remaining half of the marinade.
- Make the polenta: bring the water and the remaining half of the salt to a boil in a pot on the grill side burner or stove, slowly whisk in the cornmeal, then simmer on low, stirring often, for 25 minutes until thick and creamy.
- Thread the tuna onto skewers, alternating with the red bell pepper, green bell pepper and red onion; thread the broccoli onto separate skewers.
- Grill the broccoli skewers 8 to 10 minutes, turning, until charred and tender.
- Grill the tuna skewers 6 to 8 minutes, turning, until the tuna reaches 145°F (63°C) and the red and green bell peppers are blistered.
- Stir the Parmesan and the remaining half of the olive oil into the polenta.
- Spoon the polenta onto plates, top with the skewers, drizzle with the remaining half of the lemon juice and scatter the parsley over the top.
