Make marinade: In a large zip top bag, combine 1/4 cup olive oil, 1/4 cup balsamic vinegar, 2 teaspoons dijon mustard, 2 teaspoons garlic, 1 teaspoon salt and 1.2 teaspoon pepper. Close top and give it a little shake to mix.
Marinate: Add 1 1/2 pounds cubed chicken and close top. Refrigerate for 1 hour.
Skewer chicken: Put chicken on 6 skewers.
Grill: Preheat grill to medium high heat and make sure your grill grates are oiled. Grill for about 15 minutes, turning every 5 minutes. Cooking time will vary based on the size of your chicken chunks, but the internal temperature of the chicken should read 165°F.
Notes
Steak: This recipe also works great for a steak marinade. I like to add in 1/4 cup low-sodium soy with it and marinate a few hours. Meal prep: Freeze the uncooked, marinated chicken in a freezer-safe bag for up to 2 months. Thaw in the fridge overnight before threading onto skewers and grilling.Store: Store cooked chicken in an airtight container in the refrigerator up to 3 days.Freeze: You can also freeze cooked chicken pieces, just remove them from the skewers first then store in a freeze safe bag. Thaw and enjoy.
