In a mixing bowl, combine the 1/2 cup water, pineapple juice, soy sauce, honey, garlic, ginger, salt, and pepper. Reserve the tablespoon of water and cornstarch for later.
Add the salmon, cover, and refrigerate for 1 hour. At the same time, submerge the bamboo skewers in water for 1 hour.
Heat the grill to medium-high and oil the grates. Thread the salmon on the skewers, about 6 pieces per skewer. Pour about 1/4 cup of the marinade into a small bowl. You will use this to brush on the skewers.
Place the skewers on the grill grates. Turn each skewer 1/4 turn every 3 minutes. On the 4th and final side, only cook the salmon for 2 minutes.
At the same time you place the skewers on the grill, pour the marinade in a 2 or 3 quart saucepan. Place the pan on the grill or on the stove and bring it to a boil. Mix the 1 tablespoon of water with the 1 tablespoon of cornstarch. As soon as the teriyaki sauce begins to boil, slowly whisk in the cornstarch mix. Lower the temperature to low and continue to stir to prevent burning. Cook for about 10 minutes.
Serve with toasted sesame seeds and green onions.
While the salmon is marinating, prepare the vegetables. Place all ingredients in a mixing bowl and mix thoroughly.
Around the same time you start cooking the salmon, place the vegetables in a grilling pan or a sheet pan and place on the grill. Cook until bell peppers are tender, about 10 minutes.
Bell Peppers - I like my food to be colorful so I use a variety of color for my bell peppers, but that's not necessary if you can't find various colors.
Pineapple Chunks - fresh is best, but not required.
Canola Oil - Coconut oil or avocado oil are great substitutions here.
