In a large bowl, add water, 1/3 cup Morton Coarse Kosher Salt®, and sugar. Mix together with a spoon until the salt and sugar has dissolved. Add the chicken breasts to the salt water solution, cover and refrigerate for 30 minutes.
Remove the chicken breasts from the water, pat dry with paper towels and cut into 1-inch chunks.
Toss chicken with olive oil, onion powder, garlic powder, black pepper and remaining 1/2 teaspoon Morton Coarse Kosher Salt®.
Thread the seasoned chicken onto 8 12-inch metal skewers. If using wooden skewers, be sure to soak them in water for 15 minutes to prevent them from burning on the grill.
Heat grill to high heat, about 400°F. Place kabobs on grill, cover and cook for about 10-15 minutes, turning the kabobs 2 to 3 times until chicken fully cooked through and has beautiful grill marks.
Remove from grill and generously brush them with the honey lime sauce.
For the honey lime sauce
In a small bowl, combine all ingredients for the honey lime sauce and whisk together until the corn starch has completely dissolved and the sauce has thickened.
Notes
Don't skip out on brining the chicken. It only takes 30 minutes to ensure that your chicken is juicy and tender, so don't forget this step! During that time, you can make the honey lime sauce and get together all the other seasonings so you don't waste any time.
Try to cut the chicken pieces into same size chunks. This ensures the chicken will cook evenly and all the skewers will be done cooking at the same time.
If you're using wooden skewers instead of metal ones, be sure to soak them in water for 15 minutes up to overnight to prevent them from burning on the grill.
It's important to salt the honey lime sauce so that it isn't overly sweet. This will result in balanced sweet and salty chicken that will have people asking for seconds!
For easy cleanup, line a baking sheet with aluminum foil before brushing the skewers with the honey lime sauce. There's nothing worse than trying to clean off sticky honey in the summertime!
