Grilled Tuna Skewers with Peaches, Pineapple, & Onions

For a few hours before grilling, chunks of fresh tuna sit in a bright and sweet marinade infused with aromatics. The tuna is then grilled over charcoal on skewers with thick slices of peaches, chunks of pineapple, red onions, and red bell peppers.

Ingredients

For the Marinade:

• 2 Tbsp lime juice
• 2 Tbsp soy sauce
• 1 Tbsp oyster sauce
• 2 Tbsp vegetable oil
• 2 Tbsp honey
• 1 habanero or jalapeno pepper, (finely minced)
• 2 cloves garlic, (finely minced)
• 1 Tbsp ginger, (finely minced)
• 1 tsp kosher salt
• 1 scallion, ( finely sliced)
• 3 Tbsp fresh cilantro, (finely minced)

For the Skewer Components:

• 20 oz fresh tuna, (cut into relatively uniform 1.5” cubes)
• 3 fresh peaches, (pitted and cut into large slices)
• 1 fresh pineapple, (cut into 1.5” cubes)
• 1 large red onion, (cut into large 1.5” chunks)
• 16 oz cherry tomatoes, (left whole)
• 1 red bell pepper, (cut into 1.5” squares)
• 16 wooden skewers
• 1-2 limes, (cut into wedges, for serving)

Instructions 

• Combine all the ingredients for the marinade in a bowl.
• Mix tuna cubes gently with marinade and place in a plastic bag to marinate in the fridge for roughly 4 hours.
• Allow wooden skewers to sit completely submerged under cold water for at least 2 hours prior to skewer assembly and grilling.
• You may need to weigh the skewers down to keep them submerged under water.
• When you are ready to assemble your skewers, coat all vegetables lightly with a tiny bit of vegetable oil and season vegetables with salt.
• Assemble skewers by alternating between the tuna, peaches, pineapple, red onion, cherry tomatoes, and red pepper.
• Preheat grill to 500F.
• Quickly grill skewers until the tuna pieces are warm in the center but not cooked all the way through.
• The inside of the tuna on the skewers should still be pink in the middle when you take them off the grill.
• Serve hot, with freshly-squeezed lime.

Notes

You can omit or add whatever marinade & skewer components you prefer here.
If you are looking for a vegetarian option in place of the tuna, try this marinade and recipe with extra firm tofu.
