 1/4 cup olive oil
 1/4 cup red wine vinegar
 1 teaspoon dried oregano
 1 teaspoon chili powder
 garlic salt to taste
 salt and pepper to taste
 1 teaspoon white sugar
 2 small zucchini, julienned
 2 medium small yellow squash, julienned
 1 large onion, sliced
 1 green bell pepper, cut into thin strips
 1 red bell pepper, cut into thin strips
 2 tablespoons olive oil
 1 (8.75 ounce) can whole kernel corn, drained
 1 (15 ounce) can black beans, drained

Directions:
In a large bowl combine olive oil, vinegar, oregano, chili powder, garlic salt, salt, pepper and sugar. To the marinade add the zucchini, yellow squash, onion, green pepper and red pepper. Marinate vegetables in the refrigerator for at least 30 minutes, but not more than 24 hours.
