This is one of those recipes that came from a failure. Something didn't go right, and I was left with a massive amount of roasted vegetables. So I spiced them up with cooking creme and Italian salad dressing dry mix and lots of cheese and took them to a friends house. He grilled them (I don't know how), and together we made them into a meal fit for vegetarians and non, alike. I'm not a grillin' person, so I've included oven directions.
Dice all vegetables into bite-size (or smaller) cubes. Place in large cooking bowl.
Slather with olive oil, salt, and pepper. Mix thoroughly. Taste for proper flavoring. Repeat, adjusting oil and spices until vegetables are thinly covered with oil and flavored to personal preference. I had to mix 3 times for the oil and 5 times for salt and pepper.
Add cooking creme and salad dressing mix. Mix thoroughly.
Roast in oven for 55 minutes. Mix most of the cheese into the vegetables, leaving enough to top. Bake for another 5 minutes, or until cheese melts.
