Tuna Kebabs with Ginger-chile Marinade
The combination of plump fresh fish, juicy red bell peppers, sweet onion squares, and pungent cilantro makes for an eye-catching presentation. For additional color, thread yellow, orange, and green bell peppers onto the skewers, or you can tame the heat with thick peach slices. And feel free to swap wooden skewers for the metal variety; just be sure to give them the requisite pregrilling soak of about 30 minutes. Serve these lively kebabs with a simple green salad.
