cut kielbasa into 1" slices, cut onion, bell peppers, corn on the cob, zucchini, tomato and ANY other of your favorite veggies you like int 1/2" to 1" chunks depending on how fast that veggie might cook (example: tomato will cook fast so cut into 1" chunk), corn can be cut into 2-3" pieces.
Place all the cut up vegetables and kielbasa into a large glass bowl and pour the entire bottle of italian salad dressing over it all. Mix so everything is coated and let marinate for atleast a half hour.

Skewer the kielbasa and the vegetable, alternating meat and vegetables however you desire
