Steak and Vegetable Kebabs on the Griddle

Name: Steak and Vegetable Kebabs on the Griddle
Ingredients: 1 medium zucchini; 1 medium yellow squash; 1 red bell pepper; 1 small sweet onion; 8 oz. whole white mushrooms; avocado oil (enough to coat your sliced vegetables and oil your griddle); all purpose seasoning of your choice (I recommend Cavendar's All Purpose Greek Seasoning); salt and pepper to taste; about 1 pound of steak (cut into bite-sized cubes - We used filet, but ribeye, sirloin, or strip would work also); 1-2 tablespoons of your favorite steak sauce; 1-2 tablespoons Worcestershire sauce; 1 tablespoon minced garlic; steak seasoning of your choice - We used Cavendar's all purpose seasoning for both the steak and vegetable kebabs
