  • 4 cups cauliflower - cut into florets, 1 head cauliflower
  • 1 ½ cups red bell pepper - 1 red bell pepper, cut into chunks
  • 1 cup onion - ½ red onion sliced
  • 1 cup Italian dressing - your favorite
  • 1 tablespoon balsamic vinegar
  • 1 tablespoon extra virgin olive oil
  • ½ teaspoon salt
  • ¼ teaspoon ground black pepper


  • Mix the Italian dressing, balsamic vinegar, oil, salt and pepper in a small bowl.
  • Place the vegetables in a large resealable plastic bag. Pour the marinade over the top of the veggies. Seal tight and shake well.
  • Place the bag in a bowl. Let marinate in the refrigerator for 2 hours, turning the bag every half-hour.
  • Preheat the oven to 425°F. Spread the veggies on a baking sheet and bake the veggies for 25 to 30 minutes, stirring a couple of times during roasting.
  • Remove the roasted vegetables to a serving bowl and serve hot.
  • One serving is a little under a cup.


  • Freezing is easy.  Once cooled, you can place the roasted cauliflower in a freezer bag and keep frozen for up to three months.
  • If you decide you want to use them for dinner, take them out in the morning and place in the fridge. They will be good to use in about 2 to 4 hours.
  • When thawed, I always bake them again at 350°F for about 15 to 20 minutes. It is as simple as that!
