  • 6 large tomatoes sliced into wedges
  • 1 small onion
  • 1/2 red bell pepper or 3 mini red peppers
  • 2 cloves garlic optional, can use as many cloves as desired
  • 1 tablespoon olive oil
  • 1/4 teaspoon Italian seasoning
  • 2 teaspoons fresh basil finely chopped
  • salt and pepper to taste


  • Preheat oven to 450F and line a cookie sheet with parchment paper.
  • Chop tomatoes into wedges (quarter them or slice them into 6 wedges, depending on the size of the tomatoes). Slice the onion and red pepper. Place all of the chopped vegetables on the tray.
  • Drizzle the vegetables with olive oil and sprinkle them with salt and Italian seasoning. Roast in the oven for 30 minutes. Remove from oven and let cool.

  • *Tip: if you find your tomatoes are a bit too acidic, add a pinch (or more) of sugar to offset the acidity.
