Ingredients

• For the Fish & Veg:
• 1½ lbs firm white fish (such as salmon, mahi-mahi, cod, or swordfish), cut into 1-inch to 1½-inch cubes. Firm fish holds up beautifully on the grill!
• 1 large bell pepper (any color), cut into 1-inch pieces
• 1 small red onion, cut into 1-inch pieces
• 1 medium zucchini or yellow squash, cut into ½-inch thick half-moons or 1-inch pieces
• Wooden or metal skewers (if using wooden, see prep instructions below)
• Lemon wedges and fresh herbs (like parsley or dill) for serving
• For the Lemon-Garlic Herb Marinade:
• ¼ cup olive oil
• 2 tablespoons fresh lemon juice
• 1 teaspoon lemon zest
• 3-4 cloves garlic, minced
• 2 tablespoons fresh parsley, chopped
• 1 tablespoon fresh dill or cilantro, chopped (optional, choose your favorite!)
• ½ teaspoon salt
• ¼ teaspoon black pepper
• Optional: ½ teaspoon honey or a pinch of red chili flakes for a touch of sweet heat

Directions

1. Before You Start: Grill & Skewer Prep
2. Soak Wooden Skewers: If using wooden skewers, immerse them in water for at least 20-30 minutes before threading. This prevents them from burning on the grill. If using metal skewers, no soaking needed!
3. Preheat Your Grill: Set your grill to medium-high heat. You're aiming for an approximate temperature range of 375-425°F (190-220°C).
4. Clean & Oil Grates: Once hot, use a grill brush to clean the grates thoroughly. Then, lightly oil them with a folded paper towel dipped in a little oil (holding it with tongs!). This helps prevent sticking.
5. Pat Fish Dry: Gently pat your fish cubes very dry with paper towels. This is a crucial step for achieving nice browning and minimizing sticking.
6. Step-by-Step Cooking:
7. Mix the Marinade In a medium bowl, whisk together the olive oil, fresh lemon juice, lemon zest, minced garlic, chopped fresh herbs (parsley, dill/cilantro), salt, and black pepper. If using, add the optional honey or chili flakes. Give it a taste and adjust the salt or lemon if needed – you want a bright, flavorful mix!
8. Cut the Fish and Veg Cut your chosen fish into even 1-inch to 1½-inch cubes. Similarly, cut all your vegetables (bell pepper, red onion, zucchini) into pieces of roughly the same size. This ensures everything cooks evenly at the same rate.
9. Marinate Divide the marinade in half. In one bowl, gently toss the fish cubes with half of the marinade. In a separate bowl, toss the cut vegetables with the remaining marinade. Cover both bowls and refrigerate for 20-30 minutes. Don't marinate the fish for much longer than 1 hour, as the acid in the lemon juice can start to "cook" and change the texture of delicate fish.
10. Thread the Skewers Carefully thread the marinated fish and vegetable pieces onto your prepared skewers, alternating them for a colorful and even cook. Don't pack the pieces too tightly; leave a little space between each piece so heat can circulate around them. If your fish is particularly delicate, consider using double skewers or a grill basket for easier handling.
11. Grill Place the threaded skewers directly over the preheated medium-high heat on your oiled grill grates. Grill for about 3-4 minutes per side, turning occasionally, for a total of 8-10 minutes. The exact time will depend on the thickness of your fish. You'll know they're ready when the fish is opaque halfway up the sides and flakes easily with a fork, but still looks juicy.
12. Finish & Serve Once cooked, carefully remove the skewers from the grill and let them rest on a platter for a few minutes. Squeeze fresh lemon wedges over the top and sprinkle with extra fresh herbs. For an extra pop of flavor, you can drizzle with a little simple herb oil or any reserved (non-contaminated) marinade. Serve immediately and enjoy!
