With a soaked skewer, thread your desired line of each vegetable, alternating and adding in pieces of sausage. (This is where personal preference and creativity come into play!)
Or, thread each vegetable once with the exception of sausage and mushroom twice.
Once all 10 skewers are complete with veggies and sausage, begin the rub that will be applied to them (prevents kabobs from sticking to the grill slates).
In a small bowl, add 1/2 cup olive oil, 1 tsp. liquid smoke, 1/2 tsp. salt, 1/2 tsp. garlic powder and 1/4 tsp. pepper.
Mix to combine ingredients.
Next, use a food brush to apply oil mixture to one side of each kabob, making sure to cover all vegetables and sausages.
When the initial side is brushed & oiled, begin grilling kabobs!
