Summer Kabobs

I'm kind of on the fence on the healthy nature of these, considering the marinade has sugar and soy sauce, but so much of the sugar drains off and it goes a long way with only 1/4 cup for the entire meal, so...

It is officially summertime! I found (and slightly modified) this recipe that I found online. It was awesome and we're doing it again super soon! If you smell somone grillin' it's probably us!!

INGREDIENTS
3/4 cup soy sauce
1/4 cup sugar
1 tablespoon vegetable oil
1/4 teaspoon garlic powder
1/2 teaspoon ground ginger
2 skinless, boneless chicken breast halves, cut into 1-inch pieces
1-2 red, orange, or yellow peppers, cut into 1-2 inch pieces.
1 fresh pineapple cut into 1-2 inch pieces
1 onion, cut into 1-2 inch pieces

DIRECTIONS
Mix first five ingredients. Pour half of mixture over onions, peppers, and pineapple. Stir very well. Let sit for 5-10 minutes, stir well again. Drain/strain marinade back into original container. Pour almost all of remaining marinade (remember to keep some out for basting later!!!) into a bowl with the chicken. (If you don't do this, the pineapple will soak up too much of the marinade). Stir well, refrigerate at least 30 minutes. Start soaking skewers in water.

When ready to grill, thread veggies and pineapple on separate skewers from meat. Cook chicken kabobs 10 minutes on one side; turn, baste with additional sauce and cook for additional 10-15 minutes, turning and basting occasionally until chicken is thoroughly cooked.

Grill vegetables 10-15 minutes, turning occasionally until peppers look soft. Onions may get crispy edges, but they don't seem to soften on the grill much, so they aren't a great indicator.
