6 servings


  • 2 tablespoons balsamic vinegar

  • 1 tablespoon olive oil

  • 2 cloves garlic, minced

  • 1 teaspoon dried oregano, crushed

  • ¼ teaspoon salt

  • 3 medium zucchini and/or yellow summer squash, halved lengthwise and cut crosswise into 1/2-inch-thick slices

  • 1 large red onion, cut into 1/2-inch-thick wedges

  • Nonstick cooking spray

  • 1 cup red and/or yellow grape tomatoes


  1. For marinade: In a 3-quart rectangular baking dish, whisk together vinegar, olive oil, garlic, oregano, and salt. Add zucchini and onion, stirring to coat. Marinate at room temperature for 10 minutes.

  2. Meanwhile, lightly coat a grill pan or grill wok with cooking spray. For a charcoal grill, preheat grill pan on an uncovered grill directly over medium coals for 15 seconds. Using a slotted spoon, remove zucchini and onion from marinade and place in the grill pan. Reserve marinade. Grill vegetables for 5 to 6 minutes or just until tender and lightly brown, stirring occasionally. Stir in the tomatoes. Grill about 1 minute more or until tomatoes are heated through. (For a gas grill, preheat grill. Reduce heat to medium. Preheat grill pan as directed. Add vegetables as directed. Cover and grill as above.) Remove vegetables from the grill pan. Place on a serving platter. Drizzle reserved marinade over vegetables. Toss to combine.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
