Soak the wooden skewers for an hour or so before you plan to use them.
Heat the grill up.
Place the chicken pieces in a mixing bowl, and add in olive oil, garlic powder, onion powder and salt and pepper to taste. Stir to combine well.
Layer the veggies and chicken on the skewers in any order that you choose. The ingredients should be enough to create 10 equal skewers.
In a mixing bowl, combine the Swerve brown sugar substitute, soy sauce, lemon juice, worcestershire sauce and minced garlic. Whisk to combine.
Place the skewers on the grill with the ends of the sticks hanging off for safety and easy turning. Add salt and pepper to taste if desired.
Cook the skewers, turning once in a while to get an even cook. Continue to grill until the chicken is cooked through and the veggies are charred.
In the final minutes of cooking, use a brush to brush on the marinade to coat the skewers evenly.
Remove the skewers from the grill and serve.
