Place your bamboo skewers in a dish filled with water before you start anything else. The skewers need time to soak in some water as this will prevent them from burning when you place the skewers on the grill.
In a small bowl, whisk together all the ingredients for the marinade until well combined.
In a large bowl, place the chicken cubes and pour the marinade over the chicken. Give the chicken cubes a quick stir to ensure they are all well coated in the marinade.
Cover the bowl with plastic wrap and let sit in the refrigerator for 2 hours.
Once the two hours are up, preheat your grill to medium-high.
Take the bamboo skewers out of the water and start placing the marinated chicken cubed on the bamboo skewers. I like to put about 5 chicken cubes on each skewer.
Reserve the left over marinate, we will be using it to brush over the skewers while we grill them.
Place the lemon and Dijon skewers on the grill and brush over each of them with some of the left-over marinade. Close the lid of the grill and let cook for 4 minutes.
Flip the skewers and brush once more with marinade. Let cook for 4 minutes.
Flip the skewers one last time and let cook for about 2 minutes or until completely cook through.
Remove from the grill and place on a clean plate.
Let sit for 5 minutes, serve and enjoy! These skewers are very delicious served with tzatziki sauce and a side Greek salad.
