Heat oven to 450°F.
In food processor, place chick peas. Cover; process with quick on-and-off motions until smooth, adding enough reserved liquid (about 1/4 cup) to make a creamy mixture. Add roasted peppers, vinegar, 1 tablespoon oil and the garlic; process until smooth. If desired, season with salt to taste. Spoon into serving bowl. Let stand 30 minutes to blend flavors, or cover and refrigerate until serving time.
In large bowl, toss vegetables with 1 tablespoon oil to coat evenly. Arrange in ungreased 15x10x1-inch pan; sprinkle with seasoned salt.
Bake 7 to 10 minutes or until crisp-tender. Serve warm vegetables with hummus as a dip, or refrigerate vegetables at least 8 hours or overnight and serve with hummus.
