Mix all the marinade ingredients in a shallow dish or pan and set aside. Alternatively, you can add them to a large plastic bag and marinate that way.
Cut peppers, onion and zucchini into large chunks. The mushrooms and tomatoes should be small enough to put on whole.
Add pieces of the veggies onto a kabob skewer. Any combo is fine, I used about 16 pieces of veggie per kabob.
Add the skewers to the dish/pan or the bag if using that method.
Allow the skewers to marinate while you prepare the sides. Allow them to sit at least 15-20 minutes. You can also make this the night before and allow to marinate overnight. The longer you marinate, the more flavor the kabobs will have.
Cook the kabobs. I like using an outside grill because it gives a lot of flavor. I cooked them over a medium flame for 7 minutes on one side, then flipped and cooked another 7 minutes.
You can also cook them on a pan or oven bake them. If you bake them I suggest baking at 400 for about 10-15 minutes.
Serve with sides of choice! You can also put the veggies in a wrap or pita.
Notes
You can use any combination of peppers you want (red, yellow, orange, green), just make sure you have about 1 ½ total.
The nutrition facts are for the vegetables I used, they will change if you use others.
